a bear with a split personality...in the antarctic. it can be contrasted with a dandy lion. happy in the jungle.
Penguin #1: why is that bear so depressed? he was so happy an hour ago.
Penguin #2: dude, he's a bi-polar bear.

Lion: i love it here in the jungle.
Tiger: yeah everything is so happy.
Lion: i'd hate to live in the antarctic, i'd get so paranoid. like, everything is white and blends in.
Tiger: the animals there don't know how to deal with it.
Lion: what, like, they're bi-polar?
Tiger: yeah...bi-polar bears.
