Endacopia Fishing Guide

Answer. Finish Catthew's hide and seek, show the fishing license to the diver, and fish in six time periods: three fish per period, 18 total. Dig up the Fish Paper with the detector; completing its list and inspecting it gives the Lost Key.

The list below follows penguinleader911's illustrated All Fish guide. Day 1-3 and Night 1-3 are the six clock periods shown in that source. Leave the fishing pole after the final catch to trigger the achievement.

All 18 catches by clock period

Use the source's clock diagram to identify the period; leaving and re-entering lets time advance.

Day 1: Nautilus, Colisa Lalia, Jantic Fish.
Day 2: Peter Panini, Seahorse, Singin' Fish.
Day 3: Eel, Reddest Fish Ever, Sea Man.
Night 1: Pirate, Skele-Fish, RC Ship.
Night 2: Crab, Starfish, Big Worm.
Night 3: Drawing of a Fish, Jelly, Crate.
The blurred ??? catch does not count toward the aquarium or achievement, according to the guide.

Unlock

Three hide-and-seek spots. The last is the graveyard, where the Chameleon chases you while pretending to be Catthew. Escape to the top of the beach and meet the real Catthew, then the diver.

The yellow party wants 6 fish types. That is not the same as all 18. I keep those numbers apart on purpose.

Lost Key

Inspect the Fish Paper after all 18 fish. Finish the dollhouse puzzle, enter the smaller matching room in windowed mode (Alt+Enter), and use the Lost Key on the window that becomes a lock. Windowed mode is an intentional step, not a bug fix.

Questions I keep seeing

How many fish?

18 for the achievement and the Fish Paper. 6 is a different party threshold.

Keep going
