It's Tutter's very first day at Mouse School. He's really excited and happily shows off his bookbag and other school supplies to the other kids in the Big Blue House. Meanwhile, Bear and Doc Hogg both break down into tears over how much he's growing up. But when it comes time to go to school, Tutter is scared that he won't fit in. Bear agrees to accompany him and to wait outside the school, until he's comfortable with being there without him.
