The Brown family move to their new home after having to leave their last one because Stanley used it for one of his disgusting experiments. He's promised his mum that there will be no more exploding bogey balls, slug discos or any other revolting experiments but as the new neighbours arrive, there is a rather nasty surprise in store.

Stanley and Steph lock horns as they both want a lift from mum to go out but she cannot take them both. A plate of egg sandwiches proves to be his unlikely saviour.

Mike has an accident while testing Stanley's new invention, the 'Dizzybuster'. Stanley is forced to take Mike's place and become a junior marine; all is fine until General Crawford turns up to put Stanley through his paces. Mum's bad breath and a big juicy pimple help save the day.

Stanley is making the most revolting film ever, but first, he must find a leading lady. Daisy turns out to have unexpected talents although it soon becomes obvious that she isn't actually acting. Steph thinks she should be the leading lady and will stop at nothing to get the part, as far as she's concerned since when has lack of acting ability talent ever been a problem?

Stanley's things keep going missing, but who is the thief? It gets worse when Jess' tarantula also goes missing. The pressure's on to find the culprit and save Jess' spider before Stanley's mum spots it. A ghostly sleepover uncovers the culprit.
