- One of the items amongst Mrs. Pottage's stuff for the jumble sale is Pat's tuba.
- One of the items amongst Mrs. Pottage's stuff for the charity sale is Ted's hat, even though he is seen wearing it later on.
- At some points, Mrs. Pottage's mouth seems to be peeling.
- At first a hat that looks like Ted's appears on the floor on top of a suitcase, but then it appears amongst a pile of clothes on the kitchen table.
- When Tom is messing about with a head scarf for the jumble sale, he suddenly has eyelashes which instantly disappear a second later.
- When Pat arrives at the Vets, PAT 1 is missing its rear number plate, but it reappears when he leaves.
