Iris and Isaac are beautiful polar bears and they are best friends. However their inability to share causes them to have  a little falling out. Iris makes a snow nest which is a bit too small for both of them to snuggle up in. They each try to squish their big bottoms in, trying to get a bigger space for themselves but they end up destroying the whole nest and walking away from each other in a huff.

However they soon discover that life can be pretty sad without someone to share it with. When Iris spots a flock of snowy white ducks in flight she wishes she could tell Isaac about it – and Isaac spots the northern lights he wishes Iris was there to share the moment with him.

Can these lovely bears learn to share so they can be friends again?
