Goldfish Island Chest Map & Side Quest Walkthrough | SpongeBob Titans of the Tide
Goldfish Island is a compact, visually rich zone that rewards careful exploration and smart platforming. Between tidepools, kelp forests, rocky spires, and a half-sunken ship, the island hides a mixture of obvious and sneaky collectibles: treasure chests, hidden TVs, environmental puzzles, and a handful of side quests that unlock cosmetics or crafting components. This guide lists every chest and side quest, gives precise locations and movement tricks, and provides a tight route for 100% completion with minimal backtracking. Use the step-by-step walkthrough or pick the optimized route depending on whether you prioritize speed or thoroughness.

Map landmarks and environmental cues
Goldfish Island uses visual storytelling to hint at secrets. Look for:
a single red starfish perched away from other fauna;
a line of slightly darker sand indicating an underwater path;
isolated kelp columns that form a narrow corridor;
half-hidden buoys or ropes that mark crawlspaces. These small details are often the key to discovering chests or TVs.
Entry points and fast travel
Goldfish Island’s main entry points are Beacon Beach (east) and Kelp Basin drop (west). The central Rock Archway hub contains the fast travel unlock challenge: clearing a small environmental puzzle or miniboss will activate a waypoint. If you haven’t unlocked it yet, follow the early steps in this guide to get that done—doing so reduces backtracking dramatically.
Recommended characters and loadouts
Mobility builds: characters with double-jump or air dash are best for vertical reach.
Balanced builds: a dash for platforming plus a ranged attack for coral removal is the easiest all-around setup.
Tank/support: helpful if you want to speed through combat-heavy side quests without dying.
Upgrades to prioritize: extra dash, throw strength, and minor cooldown reductions for special attacks.
Legend: terminology used
Beacon Beach — the large sandy eastern shore with tidepools and a partial pier.
Kelp Basin — dense kelp platforms and underwater currents.
Rock Archway — central hub formed by natural twin pillars and pathways.
Reef Spires — vertical rocky columns and gust-heavy platforms.
Shipwreck Gulch — a half-sunken ship and surrounding wreckage.
Hidden Cavern — the subterranean puzzle zone and final secret chest.
Chest locations — numbered route (use this for your first run)
This route is designed to be efficient for new players: collect early chests that are on or near the main path, unlock the hub, then branch out to vertical or puzzle-based treasures.
Chest 1 — Beacon Beach tidepool overhang
Location: Start at Beacon Beach, head to the largest tidepool near the lighthouse foundation. A low stone overhang on the west rim hides a chest behind a small cluster of anemones.
How to reach: dash through the arch into the shallow alcove. Break any anemones if they block the entrance.
Tip: attacking the patrol crab nearby first prevents it from pushing you out.
Chest 2 — Driftwood Pier underside
Location: Walk east along the shoreline to the broken pier. The chest sits under the planks on the pier’s western side.
How to reach: break two loose planks (they’re highlighted by slightly different nails) and crawl beneath.
Tip: defeat or lure away the patrolling fish to avoid being knocked off mid-crawl.
Chest 3 — Shell Alcove in the cliffs
Location: South of the pier, near the tall shell statue carved into the cliff face. A small cave contains this chest behind a movable rock.
How to reach: push or throw a nearby crate into the seam and then roll the rock aside. If you lack a throw upgrade, detonate the nearby barrel.
Tip: some characters can kick the rock into the seam without an upgrade by using a charged melee.
Chest 4 — Kelp Basin shallow cavity
Location: Enter Kelp Basin via the shallow water passage. After the first series of kelp platforms, a current leads to a submerged cavity where the chest sits.
How to reach: wall-boost or chain an air dash into the cavity. The current affects trajectory—approach from the current’s edge.
Tip: timing your dash with the bubble vents makes the route reliable.
Chest 5 — Rock Archway boulder stack
Location: Return to the Rock Archway and inspect the south wall. A small stack of movable boulders hides a chest behind them.
How to reach: use grapple points to climb the ledge and then displace the boulders. A miniboss occasionally spawns during this sequence.
Tip: defeat the miniboss to prevent it from respawning and blocking the chest area.
Chest 6 — Reef Spires mid-spire coral pocket
Location: On the second spire from the archway, a patch of purple coral conceals a chest mid-elevation.
How to reach: chain a dash to a wall-climb and then perform a short double-jump to the coral pocket. Use ranged attacks to break coral if needed.
Tip: gusts from wind vents can push you off—wait for calm gusts or adjust your approach.
Chest 7 — Shipwreck Gulch stern access
Location: The half-sunken ship’s stern has a rotten panel; push aside a waterlogged crate to enter and find the chest.
How to reach: break the fasteners on the crate or use throw to slide it aside, then enter through the gap.
Tip: the interior floor is slippery—reduce momentum before precision jumps.
Chest 8 — Hidden Cavern rotating tile puzzle
Location: Beneath the island in the Hidden Cavern. A sealed puzzle door opens after solving the rotating tile mini-puzzle; the chest sits in the inner chamber.
How to reach: solve the ceiling mirror pattern (a mirrored X) by rotating tiles in sequence. The door opens and a short corridor leads to the chest.
Tip: if tiles reset, retrace to the nearest lever and re-trigger the mechanism—don’t exit the puzzle room while solving.
Full 100% route (minimize backtracking)
Follow this sequence if you want a single-session completion with the fewest repeats:
Beacon Beach — Chest 1 and NPC for Side Quest A.
Driftwood Pier — Chest 2.
Shell Alcove — Chest 3.
Kelp Basin — Chest 4; start and complete Side Quest B.
Rock Archway — Chest 5 and activate fast travel.
Reef Spires — Chest 6 and start Side Quest D; finish the three-switch puzzle.
Shipwreck Gulch — Chest 7, Chest in Captain’s Cabin, and Side Quest C.
Hidden Cavern — Chest 8 and TV 4. Return to hub to confirm all objectives.
This route keeps vertical climbs grouped and ties side quests to nearby exploration so they’re completed while you pass relevant areas.
Side quests — step-by-step walkthroughs and rewards
Side quests are short, often multi-step, and usually reward unique cosmetics, recipes, or crafting fragments. Many tie directly into chest locations or require environmental interaction.
Side Quest A — The Lost Locket
Start: NPC Pearl on Beacon Beach boardwalk.
Objective: Recover Pearl’s locket stolen by a mischievous crab.
Steps:
Defeat the crab at the tidepool — it drops a torn map piece.
Use the map piece as a hint to a driftwood pile near the pier; break a board to find the second piece.
Combine both pieces to reveal the shallow cavern in Kelp Basin; the chest there contains the locket.
Reward: bronze necklace cosmetic, upgrade fragments, and a small coin pile.
Tips: the crab sometimes carries the map; don’t fast travel until you inspect the tidepool after the fight.
Side Quest B — Kelp Kids’ Race
Start: Kelp Kid near rainbow kelp in Kelp Basin.
Objective: Beat the trial time using boost pads and bounce mushrooms.
Steps:
Learn the boost pad timing; pad intervals are consistent and can be memorized.
Use the inner racing line around the first bend and save dash for the final hoop.
Avoid the outer kelp nodes which slow you down.
Reward: cosmetic sticker and a chest with crafting parts.
Tips: practice once and memorize the bounce mushroom cadence—this cuttime trick makes it repeatable.
Side Quest C — Shipwright’s Request
Start: Shipwright NPC at Shipwreck Gulch.
Objective: Gather three rotting planks across the gulch.
Steps:
Under the pier — use a jump-throw to pry up an embedded nail.
Floating debris field — use grapple or double-jump to reach the plank on a drifting crate.
Captain’s cabin — unlock the loose floorboard to find the third plank.
Reward: blueprint and upgrade shards.
Tips: clear the small enemy clusters first; planks are sometimes shielded by minor spawns.
Side Quest D — Old Fisherman’s Tale
Start: Old Fisherman on a windblown ledge in Reef Spires.
Objective: Solve the three-switch puzzle spanning the spires and retrieve an heirloom rod.
Steps:
Activate left switch at the base of the south spire using gust platforms.
Destroy coral blocks to access the central switch in a pocket; flip it.
Grapple to the floating platform with the right switch and finish the sequence.
Reward: heirloom rod cosmetic, rare crafting component.
Tips: sequence order is fixed; mark switches on your minimap to keep orientation.
Hidden TVs and lore
TVs unlock short cutscenes and lore entries and are often placed in vertical or tucked-away spaces. Locating them is optional for completion but required for completionists.
TV 1 — Lighthouse basement: crawl through sand vents to reach the projector.
TV 2 — Mid-spire coral pocket: the same pocket as Chest 6 hides a small TV behind purple coral.
TV 3 — Ship deck projector: lift the loose deckboard to find a tiny screen.
TV 4 — Hidden Cavern pedestal: revealed after solving the rotating-tile puzzle.
Search tips:
Scan above and below the main path.
Look for small crawl entries and slightly displaced fauna.
Use short-range scanning abilities if your character has them.
Combat tips and enemy encounters
Goldfish Island mixes predictable, low-threat enemies with a few tougher ambushes and a miniboss.
Patrol Crabs: use dash-stun combos or bait them into hazards.
Kelp Worms: wait for the pop-up then strike—don’t spam attacks.
Armored Pufferfish: use charged throws or environment explosives.
Reef Golem miniboss: slow movement, telegraphed attacks—kite and hit weak points between animations.
Environmental combat:
Use explosive barrels and falling rocks to conserve resources.
Clear enemy spawners before entering chest alcoves to avoid knockback or interruptions.
Platforming tricks and advanced movement
Wall-bounce chain: bouncing off a wall into a double-jump will reach many mid-elevation pockets.
Current riding: angle into the current gently to land on hidden platforms at the current’s edge.
Grapple swing arcs: use the anchor point’s far edge for maximal swing height and distance.
Momentum control: reduce speed before narrow ledge jumps to avoid sliding off slippery surfaces.
Practice these moves in Kelp Basin’s training nook before attempting the Reef Spires sequences.
Common problems and fixes
Chest unreachable due to invisible lock: check nearby switches or clear spawners; some chests are gated by area clears.
Side quest NPC not present: defeat local enemies or leave and re-enter the area; NPCs sometimes spawn only when the area is safe.
Puzzle tiles reset mid-solve: find the nearest lever and re-trigger the mechanism; avoid leaving the puzzle room while the mechanism is active.
Optimized single-session run (time-efficient)
Beacon Beach: Chest 1 and Side Quest A.
Driftwood Pier: Chest 2.
Shell Alcove: Chest 3.
Kelp Basin: Chest 4 and Side Quest B.
Rock Archway: Chest 5 and fast travel unlock.
Reef Spires: Chest 6 and Side Quest D.
Shipwreck Gulch: Chest 7, cabin chest, and Side Quest C.
Hidden Cavern: Chest 8 and TV 4. Return to hub and confirm objectives.
This minimizes repeated vertical travel and lines up side quests with nearby chests.
Replayability, challenges, and achievements
Speedrun routes: once you know the wall-bounce and current lines, map out precise times for a speedrun challenge.
Self-imposed restrictions: try melee-only or no-dash runs for a tougher experience.
Completionist runs: collect all TVs and cosmetics for extra achievements and lore.
FAQ
How many chests are on Goldfish Island?
Goldfish Island contains 8 primary chests plus several small hidden mini-chests and 4 hidden TVs for lore.
Do I need a specific character to reach everything?
No single character is required, but mobility-focused builds with double-jump, air dash, or grapple significantly reduce difficulty for vertical sections.
Are side quests missable?
Side quests can be missed during a first pass if you fast travel away before talking to NPCs. The island is revisitable; use the fast travel point to return and finish missed quests.
Where is the final secret chest?
The final secret chest is in the Hidden Cavern behind the rotating tile puzzle; align tiles to form a mirrored X and the sealed door will open.
What should I do if a chest is behind a regenerating coral?
Destroy the coral and finish the chest area before leaving; some coral regenerates after a time, so complete the interaction once it’s cleared.
How do I find hidden TVs?
Search vertically and in narrow crawlspaces. TVs are often slightly off the main path or hidden behind destructible decor.
Closing notes
Goldfish Island is short but dense: a few minutes of careful search around the tidepools, kelp columns, and shipwreck will yield most chests, while a couple of clever movement tricks open the rest. Keep your eye on vertical spaces, use environmental cues, and prioritize unlocking the fast travel hub early.
