The Everywhere Bear by Julia Donaldson

The Everywhere Bear has a wonderful time with the children in Grade 1, but one day he gets more than he bargained for when he falls unnoticed from a backpack and embarks on his own big adventure! He gets washed down a drain and whooshed out to sea, rescued by a fishing boat and loaded onto a lorry, only to be carried off by a seagull! How will he ever make it back to his classroom?
