Alright, lets replace talking animals with "this hungry animal wants food". If it is going to be about Slapstick humor, then it is all execution and originality on a per joke basis (but you are right, hopefully this is a liitle more than just jokes, that'll probably be territory that has been charted before ), whether it is a similar idea like a predator like the Coyote or Sylvester the cat, if it is all about funny stuff going on, then the concept is just a pretext. I don't see the execution here being similar to Inside Out, though, it strikes me as being more like the gag where one character ends up becoming a puppet of someone else.
