There is an exciting new Ghost Coaster inside the sofa, but Lloyd, PB and Abacus are too short to go on it - however, Lloyd refuses to allow his height to get in the way of fun, and so he devises a way to make the three of them appear tall enough to ride it.

As an anniversary treat, Gena has booked a private performance by Dolichovsky, Malcolm's favourite actor - Lloyd is entrusted with preparing the apple for the snail's arrival, but Dolichovsky proves to be far more demanding than expected.

After his inattention causes a mid-flight collision with Polly, Lloyd must attend a 'flight awareness' course run by Molly - if he refuses, he risks being grounded and will therefore have to walk everywhere!
