 We don't see many animals in the coldest parts of the world, but polar bears, which are white, live in really cold places. Brown bears sleep when the weather is very cold. 

They don't wake up or eat any food. 

When the weather starts getting cold, some birds fly to hotter countries, but penguins are very happy in the snow!

Snowshoe rabbits are really clever! When the weather's very cold and there's snow on the ground, this animals's fur changes from brown to white!
