On the Buses: The Inspector's Pets

It's goodbye to the depot for a while for Blakey - he and his mum are going on holiday. But they can't find anyone to look after the dachshund (Mitzi) and the tropical fish until Stan volunteers.

The tank gets broken but Stan replaces it with one made from the bus windscreen and the fish are safe so Blakey does not notice the difference. However, Arthur has let Mitzi play with the pub's - male - Dalmatian and she has put on weight by the time Blakey reclaims her.
