I think both should be implemented, bird because PT's default screen is a bunch of emptiness which it could fly in, and fish to extend on this PT life thing.
We'd need more though, maybe demon worms inside solids, tigers on solids... etc
we could also move the 2 stickmen into a new section with all the non volatile life
If they would put a meat on TPT, you could get the Fish Bait thing working. Mabye if you added salt to the meat? Bird is a no-no. Wouldnt be realistic.To have random directions in a bird is not workable because a bird is smart enough to realize what is in front of it and avouid things like fire. Do the Fish grow and die? I could have a aquarium!!! YEA!!!!
