Meet Knut - a three-month-old polar bear cub who's at the centre of a big row in Germany after he was rejected by his mother.
Knut's being looked after by a keeper at Berlin Zoo who makes sure he is fed properly and has plenty of time to play.
Some people say the zoo should have let Knut die, because they think it's wrong for wild bears to be raised by humans.
But polar bears are endangered and the zoo says looking after Knut could help to increase their numbers.
Knut's story has been massive in Germany but all he's worried about is what he'll get to play with next!
