Overview: When Little Bear accidentally breaks a wheel on Zebra’s cart, Old Bear finds a box of shiny, round lids to mend it. There are enough lids left over to make a lovely go-cart. When it is finished it turns out that Ruff is too big and needs a bigger cart of his own. But there are only two wheels left. Old Bear hunts in the cupboard under the stairs and finds a wheel that is much bigger than all the others. You can’t make a go-cart with only one wheel but what Old Bear does make is even more fun.
