Our Friend Hedgehog: the story of us, by Lauren Castillo
Mutty is lost in a storm and Hedgehog must find him. Hedgehog follows a trail to find her dear stuffed animal, and on her journey makes six new friends who step up to help. I'll admit that I didn't realize Mutty was a toy in the first chapter, which caused me some anxiety thinking of young readers. When I recommend the book in the library I make sure to point that detail out, but it's probably not necessary since kids are so quick to understand nuances in illustrated books.
