Fishipedia stuck at “all but one”? The official Patch 1.0.5 notes fixed the bug that required one extra Drip. Do not farm an invented extra entry on a current build; use the Fishipedia troubleshooting note to audit uncertain kills. Read the official patch notes ↗

Post-game cleanup route

The new public achievement route suggests finishing the story first, then returning to cleanup with late-game gear. That is a useful route idea, but the source was written on v1.0.4 and its old shortcut notes were patched in 1.0.5. Treat the return-to-Island-1 state as an author reference until it is replayed on v1.0.11.

Cleanup groupCandidate method from the public guideEvidence state
Collector / FishipediaOpen the Tab encyclopedia to see missing creature and drip entries; use it as a checklist before hunting.Author reference / replay pending
Yummy in my tummy / Competitive eatingBurn a mini-boss, then eat it; the source says the two conditions can be combined in one cleanup attempt.Needs-verification
All in / Rich! MillionaireUse a high-value cooked catch for a roulette attempt, but do not rely on the source's exact multiplier, odds or cash threshold.Needs-verification
I'm the bird now / Everyone's dreamSet up the boat or a seagull bait with dynamite; the exact trigger and safe distance need a current replay.Needs-verification
HandymanCandidate route: lower the final boss with weapons, then make the killing hit with fists. Co-op attribution is conflicting in the source comments.Conflicting community reports
BeanKeep this on a separate speedrun save. The source explicitly says its older shortcut was patched, so do not reuse its old timing route.Version-bound
Why this helps: use the source as a cleanup checklist, not as current balance data. The official Steam page remains the authority for the 31 names and descriptions; method claims need a current replay or an independent cross-check.

Evidence and completion rules

The official Steam page confirms the total count, names and descriptions. Public completion guides can suggest methods, but a single community route is not promoted to fact when it conflicts with another report or lacks a current replay. Exact creature lists, hidden conditions, timer edge cases and drop requirements remain needs-verification.

Version note: v1.0.9 adds difficulty modes. Record the mode for timed, boss-speed and combat achievements; older guides may not match current health or damage modifiers.
