Fish tokens

[D. Boon's Ghost]

I was curious if any of our fellow fans have found a use for the fish tokens in the game?

I am two years late to the IfOS party, but I got the game this past Christmas and have fallen in love with it. The only thing that bugs me is the fish pickup for the bear tent (along with the magic wagon pickup). While I am guessing it is a reference to a future expansion, it seems odd that the Frog would word L Board pickups with things not in the base game.

If you made the three fish tokens one time use, would giving each of them the ability to heal one of JoJo's wounds be too powerful? As it is, the bear is already quite the dancing mauler. To balance it, perhaps ban cabbage from JoJo's diet?
