Open Sea For Animals!

Open Sea For Animals! animals / bestiary notes

What this gets you: Animals sit in base pens and earn Cash (including offline). Index is the discovery log. PARTIAL samples only — not a full $/s ladder.

Run order

  1. Park animals in base pens so offline Cash ticks.
  2. Open the right-side Index book for discoveries.
  3. Treat HUD floaters and creator narration as PARTIAL samples, never a closed bestiary.
  4. Never import Brainrot pet names or codes.

How animals pay

  • Official description: Use Animals to Earn Cash · Your Animals earns Cash offline.
  • HUD banner repeats offline totals (footage samples from hundreds of K$ to multi-T$ depending on progression).
  • Pen labels / float text show per-animal rates when zoomed — OCR samples only below.

Offline Cash is the bridge between sea runs. Parking a Bat (or any hatch) before you leave the base is the reason the first-session guide puts Codes first.

Sample animals / incomes (HUD or clear narration — PARTIAL)

Animal / note Sample lock Source type
Bat Animal Code reward · placeable starter collectible Redeem toast + icon
Early frog / chicken line Starter hatch path; early ~100$/s class feedback on one F2P clip Caption + HUD (early only)
T-Rex / shark / eagle-class pens Visible in late base pens with large $/s floaters HUD (late session — not starter rates)
Polar bear (end-game sample) Creator narration ~172B$/s after max-zone haul Caption only — treat as late Robux-accelerated sample

Do not sort a “best animal” tier list from a single OP-pack video. Prefer your Index + pen labels.

Index

Right-side Index (blue book) is the discovery log. Full discovered/% tables were not OCR-locked into a clean roster this dig — listed as unknown. Until a clean Index OCR exists, any public “complete bestiary” is invented.

How to read PARTIAL samples

  • Early F2P rates and late Robux-accelerated rates are different games of scale — never average them into a tier list.
  • Floater text can include temporary boosts / rebirth multis; treat OCR as a snapshot, not a permanent table.
  • Brainrots collectibles and income models do not transfer. Wrong Place = wrong animals.

What we do not publish

  • Invented full Index $/s roster
  • “Best animal” ranks from one OP-pack video
  • Brainrots pet names or codes
  • Pro / purchase CTAs or Unverified badges
