After Roz loses a foot saving Thorn, Mr. Beaver examines her stump and identifies the practical problems: the replacement foot must grip the ground, last a long time, and attach securely to Roz’s leg. Brightbill anxiously asks whether Roz will walk again, but Mr. Beaver is confident and excited by the challenge.

Mr. Beaver brings a hard section of tree trunk from the pond and begins shaping it into a bootlike wooden foot. Chitchat chatters from a branch, comparing Roz’s situation to a lizard growing a new tail, while Mr. Beaver carves, tests, and adjusts the wood until it fits Roz’s stump.

Mr. Beaver then calls in help. The raccoons Bumpkin, Lumpkin, and Rumpkin bring vines and use their nimble hands to tie the wooden foot tightly to Roz’s leg. Next, the woodpecker Trunktap pecks holes in a pine tree so sticky resin can ooze out; Mr. Beaver spreads the resin over the foot and vines to seal the attachment.

Roz is delighted and begins walking around her garden, seemingly restored. However, the first attempt fails within a week when the vines loosen and the foot slides out of place. Mr. Beaver, Trunktap, and the raccoons return determined to improve the design.

The helpers use harder wood, tougher vines, and boiled resin that thickens into a powerful glue. After continued tinkering, Roz finally receives a reliable wooden foot. Although Roz walks more slowly and with a slight limp, Roz can move again, bringing relief to Brightbill and the other animals.
