The WotWots are pulling funny faces and laughing when someone else starts laughing with them. They set out to find who is laughing so loudly.
SpottyWot is convinced he has discovered an animal with two heads. DottyWot is delighted, and they set off through the zoo to try and find it.
SpottyWot thinks a big digger that is laying drains at the zoo is a large, hungry animal. When he is told it is not an animal he is disappointed.
The WotWots try to draw some pictures in the dark, but it proves rather difficult.
