Norman, Mandy, Sarah and James are having a sleepover at Mandy's house. But when Dilys accidentally packs his Cuddly Sheep Pyjamas instead of his Army Bob Pyjamas he has to hide them.

Whilst doing some kite flying with the other kids, Mandy is inspired to want to fly over Pontypandy Mountain. Hannah tells her that her dad, Joe Sparkes, has just the thing...which turns out to be a hot air balloon!
