Finn was born a biter and will die a biter.
He seems to follow an ‘opposite day’ approach to life, doing unexpected things in order to subvert social order. For example, when people expect him to be a ferocious carnivore, he behaves like a silly dolphin.
Is he a genius commentator or a brainless buffoon? No one knows. Either way, he loves the zoo’s current chaotic situation and can’t wait to bite some rears.
