SpottyWot's attempt to scare his sister with a loud roar is not very scary, so the WotWots head out to find an animal that SpottyWot can copy.
SpottyWot discovers how to make new colours by mixing paint. He then meets an animal that can change the colour of its whole body!
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.
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.
