Bob and Wendy are building a bus stop, when Roley almost runs over a tortoise. Roley is entranced by the creature and christens him "Timmy", but Bird is unhappy to find himself supplanted in Roley's affections. Bob takes Timmy back to the Yard, saying they must return him to his owner. Bob starts to build a tortoise run, but is distracted by the arrival of Farmer Pickles and a trailer full of lettuce. Unseen, Timmy finds his way into the trailer and chomps happily as Travis drives away. Dizzy finds Mrs. Potts looking for her escaped tortoise "Tommy", and proudly leads her back to the Yard, only to find that Tommy has disappeared again. A frantic search is interrupted by Farmer Pickles, who has found an intruder in Travis's trailer. Delighted, Mrs. Potts takes Tommy back home, but promises that Roley can visit whenever he wants.
