Dr Knowles and Professor McCork ask the question 'Could pineapples grow on the moon?' while battling with a lack of oxygen, homesickness and some bad chocolate etiquette. Colin and Ms Hucklebuck remain at Ground Control in the Brain Freeze studio and hope that there isn't a bad atmosphere.

Judge Knowles presides over the Brain Freeze court to try to solve the mysterious disappearance of Ms Hucklebuck's tooth, which she had left out for the Tooth Fairy. There has to be a simple explanation and also an answer to the question 'Why do we have baby teeth?'.

Brain Freeze broadcasts live from the seaside and asks the question 'Why is the sea salty?' All is going well until McCork introduces his new sidekick Rocky the seagull and suddenly it gets a whole lot harder for floor manager Colin to keep the show on the road.
