Blueball lives !
Ahem, just good to see him not dead.
So what happened to the griffin after the show ended?
He is a member of staff so they patched him up and got him back out there for the next show. Puffygriffins love hunting fluffies and this was one of the few times it has been injured.
He has a dedicated care taker that bring him home on the off season.
These could be the pics used at the end of story to explain some future events like in American Graffiti.
