Repeat After Me Little Robots : Season 4 Episode 12

Stripy knows he's holding Tiny and the others up when they are busy building, so he decides to adjust his circuits to make himself go faster. The others are very surprised when he strides past, very fast - and then again and again. Tiny realises Stripy has managed to put himself into repeater mode and confusion mounts. Tiny engineers a solution and the Little Robots are happy to have the Stripy they know and love restored to them.
