S01E07 Horrid Henry's School Fair

Mum is busy planning the school fair and needs some secondhand games and toys—specifically, those belonging to Henry and Peter. Eager to part with his Walkie-Talkie-Burpy-Slurpy-Teasy-Weasy Doll, Henry happily donates it, relieved to be rid of it. With a bit of clever investigation, he discovers the ultimate treasure hidden on the Treasure Map. Everything seems perfect. But will it stay that way?
