Each SEA entity in Clean the WORLD! with its official claim, the strongest available evidence, and an explicit label where documentation ends — checked 2026-10-17.
Four entities belong to the SEA chapter. SEA itself is the ocean area after the land eras — entry documented at ~1,000,000 gum. Seagulls and the shredder are named by the official description but undocumented in every mechanic that matters. The turtle milestone is the badge that proves you crossed: Turtles Don't Eat Plastics Silly, 976,019 awards, 71.8% win rate — the game's first genuine grind wall. One more SEA-era fact: the badge "I'm Above The World" (Outer Space) was created the same day and still has zero awards.
| Entity | Type | Documented (source, checked 2026-10-17) | Undocumented |
|---|---|---|---|
| SEA | Chapter / environment | Official update and environment name; the current chapter after the land eras. Entry documented at ~1,000,000 gum (LITTY video, 2026-08-21 — pre-rebirth, pre-PRESTIGE). | Official entry price (if it changed), map layout, and whether PRESTIGE rebalancing altered the area. |
| Seagulls | Creature | Named in the official description's SEA feature list (Roblox game page). | Behavior, spawns, effects on income, and rewards — nothing public documents any of it. |
| Shredder ("SHREADER") | Machine / upgrade line | Named in the same official list; shredder-line upgrades appear among the endgame maxing targets in RussoPlays' ~September 2026 video. | Function, inputs, outputs, unlock requirement, rate, and cost — the game's least-documented feature. |
| Turtles | Milestone (badge) | "Turtles Don't Eat Plastics Silly" — "You unlocked the SEA!"; 985,177 awards, 71.8% win rate (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)). | Exact unlock condition (the gum figure is community evidence) and any in-area turtle content. |
Every land-era badge before it is graduated by nearly everyone who reaches it — win rates of 99.9–100%. The turtle badge breaks the pattern at 71.8%: almost 700,000 players who earned the dinosaur badge never crossed into the SEA. In a game with no combat and no fail states, that statistic is the difficulty curve — the million-gum gate is where casual play ends and stockpile planning begins.

The developer spells the machine "SHREADER" in the official description — searches for the correct spelling still find the feature, but fan posts use both. That is also why this page repeats the official strings exactly: seagulls, SHREADER, and MORE UPGRADES are quoted from the description rather than cleaned up, because they are the game's own labels and the only names every player shares.
The listing's own numbering — Underground as Chapter 3 (teaser since removed), Outer Space as Chapter 4 — places SEA as the second released chapter, after the land-era base world. That makes SEA the game's middle age: old enough to have its own badge, its own economy anecdote (the million-gum gate), and endgame references in later videos; young enough that PRESTIGE-era balancing (2026-09-27) still applies to it. Two entities were created into the badge list on the same day as SEA's — WELCOME and the unreleased Outer Space award — which is how we know the chapter structure was designed as a ladder, with "I'm Above The World" reserved from day one for the chapter that still has no release date.
You can audit anything this page says in under a minute. The badge row lives in Roblox's own badge list for the game — open the game page's badge section or call the public badges API with universe 10,494,847,029; the award count and win rate update in real time. The SEA feature names are quoted verbatim from the official description on the game page — read the description block and you are reading our primary source. The one community-sourced number, the million-gum entry, is checkable the old way: reach the dinosaur era and read the game's own SEA prompt. If your in-game figure differs from what a video claims, your screen wins; tell us via the contact page and the table gets your correction with a new checked date.
Said plainly so nobody mistakes this page for a complete reference: the developer has never published SEA mechanics. No source documents what seagulls do, what the shredder shreds, what the SEA area's map contains, or whether the gum entry changed after rebirth (2026-08-25) and PRESTIGE (2026-09-27). When the developer updates the description or a credible capture surfaces, the SEA update guide and this page get the details with a new checked date. The updates page is the watch point for that.
The latest released chapter — an ocean environment you enter after the dinosaur era by stockpiling about 1,000,000 gum (community-documented entry cost). Unlocking it awards the 'Turtles Don't Eat Plastics Silly' badge.
Seagulls are named in the official game description's SEA feature list, so they exist as SEA content — but their behavior, spawns, and rewards have never been documented by the developer or captured in available footage.
An officially named SEA feature (the developer spells it 'SHREADER'). No public source documents its function, inputs, outputs, unlock, rate, or cost. Late-game videos reference shredder-line upgrades among endgame maxing targets, but a verified explanation does not exist.
'Turtles Don't Eat Plastics Silly' — description: 'You unlocked the SEA!'. It is the SEA unlock milestone: 985,177 awards at a 71.8% win rate, the first badge in the game below 100%.
985,177 at the October 17, 2026 check — about 27% of everyone who joined, versus ~46% who reached the dinosaur era just before it. The gum grind between those two badges is the biggest drop-off in the game.
