Clunky Wilson / Old Puffer Pete's Tour

S1, E304: Clunky Wilson: Wilson and Koko are having loads of fun racing each other – until Wilson damages his wheel! He’s scared of going to the repair shed to get it checked out, so he tries to put on a brave face and ignore the problem. Old Puffer Pete's Tour: Koko is yearning for adventure – and she just might get it, as today the chuggers are making deliveries out of town. But Vee asks Old Puffer Pete to accompany them – and he’s so SLOW.
