Bob's Boots is the first and premiere episode of the third season.
Bob has got new boots, but they squeak because they need wearing in, so when he sets off with Lofty to fix a gate, he walks to the job. At lunch, Bob's squeaky boots attract the attention of three mice, but he does not know it. Lofty sees the mice at Bob's feet and makes a run for it with Bob chasing after him, unaware that there really are mice at his feet. When Bob catches Lofty at the yard, he realizes that there are indeed mice following him. Spud and Bird race in, and Spud eats his cream bun, dropping crumbs. The mice circle Spud's feet, squeaking for more.
In the UK Version, Bob has a Cheese and Chutney in his lunchbox. In the US Version, It is change to a Peanut Butter and Jelly sandwich, probably because Cheese and Chutney would be unfamiliar with American viewers.
