We just learned a little about Earthworms.
Squirrels are fuzzy little crazy creatures that can scramble up and down trees almost faster than you can see.
Just think how crazy it would be if squirrels could fly!
There really is such a thing as a flying squirrel, but it doesn't really fly as much as it glides, kind of like a paper airplane.
The flying squirrel has skin between it's arms and legs, called patagium, just like a bat's wings.
(from: wikipedia - flying squirrel)
When it jumps from one tree to the next, it spreads out its arms and legs to glide through the air.
