Kitchen Whiz Bob the Builder : Season 19 Episode 3

Bob is in the kitchen preparing lunch for the team when a hungry Pilchard sneaks into his bag and hitches a ride to work. The day's job is at Chef Tattie's UFO-themed revolving restaurant, where Bob is building the kitchen, Wendy is wiring the revolving floor, and Leo and the machines are decorating the entrance. Pilchard climbs out of Bob's bag and causes strange things to happen on the site, prompting the Machines to think there is an alien. When the restaurant starts revolving at high speed, Bob saves the day by luring Pilchard off the remote control with a sandwich. Together, the team finishes the restaurant in time, and the Machines discover that the "alien" was actually Pilchard.
