Good game, just some questions... – Fishy Bits Review

I like this game. It’s challenging but not rageworthy. My only problem is that there are these collectibles in the game that are a little rarer than the coins, they look like cans of fish-flavored cat food. I’m not sure what you’re supposed to do with them. There’s no tutorial or help pages online, are they just there to collect for no reason? I have almost fifty of them and I still have no clue what to do with them. A wiki page online, an in-game popup, or a description update would solve this problem.
