When a tree grows

"When Moose sees the inviting tree where Squirrel has built his nest, he rubs his itchy antlers against the trunk--and sets in motion a chain of comic catastrophes. The tree falls and wakes Bear, who stumbles into Moose, who causes a truck driver to swerve off the road. But then Squirrel jumps onto that truck and ends up in the city, all alone. Who will help him get home? And how will Squirrel thank them?"--Amazon.com.
