SEA update guide

Clean the WORLD! SEA Update: Seagulls, Shredder & Turtles

Everything checkable about the SEA chapter — the entry cost, the badge, the officially named features, and precisely what the game has never documented — checked 2026-10-17.

Quick answer

The SEA is the chapter after the dinosaur era. You enter it by stockpiling about 1,000,000 gum (documented by community footage; the developer has never published the price). Crossing the line awards the Turtles Don't Eat Plastics Silly badge — "You unlocked the SEA!" — and the official description ties three features to the update: seagulls, a shredder, and more upgrades. Two updates have shipped since (rebirth on August 25, PRESTIGE on September 27), but SEA is still the newest released chapter; its badge win rate of 71.8% makes it the game's first real grind check.

Getting there: the gum budget

The recorded entry price is a seven-figure gum stack, and the badge data shows the wall: 1,670,923 players earned the dinosaur badge but only 976,019 ever unlocked the SEA — a drop of roughly 700,000 players at one gate (Official (badges.roblox.com API, universe 10494847029 — award counts checked 2026-10-17 (unchanged from the 2026-10-09 reading); win rates checked 2026-10-03, masked on the 2026-10-09 and 2026-10-17 rechecks)). Convert your own pace into a plan with the calculator: at 400 gum per minute, the final 750,000 gum is about 31 hours or 42 forty-five-minute sessions. That is the actual cost of the chapter in the only unit the game respects.

Skill-tree chance nodes are the multiplier that matters most while saving: golden-drop rolls (a ~2% golden poop at 100x value was the recorded standout) convert spare minutes into big gum swings without touching your base rate.

The badge: Turtles Don't Eat Plastics Silly

Every era badge before SEA sits at a 99.9–100% win rate — you get them by playing. SEA's 71.8% is the first number that says "you can stop here", and the name itself is the chapter's theme statement: the SEA exists because plastic and trash reached the ocean, and turtles are its mascots. The badge was created August 19, 2026, alongside the era badges, when the game was titled "Clean the WORLD! [SEA]".

The officially named SEA features

The official description's SEA block names three things. Here is each one with the strongest evidence available — and an honest label where the evidence stops:

Feature	What is documented	What is not (as of 2026-10-17)
Seagulls	Named in the official description's SEA feature list (source: Roblox game page).	Behavior, spawns, effects, and rewards have no public documentation — no developer note, no captured footage detail.
Shredder (spelled "SHREADER" by the developer)	Named in the same list; late-game videos reference shredder-line upgrades among the endgame maxing targets (RussoPlays, ~September 2026).	Function, inputs, outputs, unlock requirement, rate, and cost — all undocumented. We will not invent a formula.
More upgrades	Named generically; PRESTIGE later made every Robux upgrade obtainable free-to-play (September 27, 2026).	Which specific upgrade tiers shipped with SEA versus later patches is not separable from public information.

What SEA changed about the game

SEA is where Clean the WORLD! stops being a single-map grinder and becomes a chaptered world: it is the bridge between the land eras and the coming Outer Space (Chapter 4). The chapter numbering the listing itself used — Underground as Chapter 3, Outer Space as Chapter 4 — places SEA as the second released chapter, although the developer has never printed an official "Chapter 2" label on it. Practically, SEA players report a different environment to clean, and PRESTIGE-era balancing applies there like everywhere else: pay-to-win is gone, so the chapter is a time investment, not a wallet check.

What PRESTIGE changed for SEA players

SEA's economy advice aged through two patches, and the second one matters most. Rebirth (August 25, 2026) added a reset layer beneath the chapter climb — your first rebirth can now sit before, during, or after the SEA grind, and the TIME TRAVELER badge's 32.6% win rate suggests most players stack it after. PRESTIGE (September 27, 2026) hit closer to the wallet: every upgrade that used to be Robux-gated is now obtainable free-to-play, which converts SEA from the pay-to-win era's "pay or grind longer" into a pure planning problem — exactly what the gum-budget table above solves. What neither patch published: whether the SEA entry itself got cheaper, pricier, or stayed at the recorded 1,000,000 gum. That number stays flagged as pre-PRESTIGE evidence on this page until a fresher source exists.

Questions players ask

How do I unlock the SEA in Clean the WORLD!?

Community footage (LITTY, 2026-08-21) documented the SEA area entry at 1,000,000 gum. Clear the dinosaur-era skill tree, then stockpile gum — roughly 46% of players reach dinosaurs, but only about 27% ever unlock the SEA, so the grind is real.

What is the SEA badge?

'Turtles Don't Eat Plastics Silly' — description: 'You unlocked the SEA!'. It is the only milestone badge with a win rate below 100% before rebirth (71.8%), which makes it the first genuine skill/grind check in the badge list.

What are seagulls in Clean the WORLD!?

Seagulls are named in the official game description's SEA feature list. Their exact behavior — spawns, effects, rewards — was never documented by the developer and is not covered by available footage, so we describe them by name only.

What does the shredder do?

No public source documents the shredder's function, inputs, outputs, or cost. It is an officially named SEA feature (the description's 'SHREADER' spelling is the developer's), and late-game videos reference shredder-line upgrades, but a verified explanation does not exist yet.

Is SEA still the latest update?

No. After SEA came the rebirth update (August 25, 2026, TIME TRAVELER badge) and then PRESTIGE (September 27, 2026), which made all Robux upgrades free-to-play. SEA remains the latest released chapter; Underground has no live teaser and Outer Space (Chapter 4) is announced but unreleased.
