the pet pal and persuasion required on your main
This sucks for our coop game, my friend is the host, I'm player 2 and I have pet pal. The squirrel won't talk to the guy who speaks squirrel, so we are at an impass.
As for his health... it's fine if he can die, but at least give him some shields or make him immune to surfaces. If a dragon fireballs him, cool, ghost squirrel it is, but a poison pool under a vine i climb shouldn't be certain death. At least give him the ai that lets him doge that like the monsters have, or let the cat jump over.
