Marine Compendium

The Marine Compendium is an encyclopedia from Make a Good Mega Man Level 3 that covers fish-adjacent robots. It can be obtained from the start by gaining access to FREE FISH Inc., a marine research installation located underneath Tier 7's forest. Filling out the Compendium requires unlocking Contest Weapon Data and using Bait Bobber to catch robots. After all 96 entries are filled, the Fish Fiend gives Mega Man the Wonder Hook - a merely cosmetic "upgrade". The "Habitat" section helps when it comes to tracking certain robots, assuming if listed stages were visited first. Certain regular enemies, main bosses and mini-bosses count for Marine Compendium's completion.
