Geronimo Stilton - Season 1 Episode 8
Hypno Tick Tock

Geronimo is overworked and needs to relax. After Trap notices an ad for a hypnotist who specializes in helping people relax, Geronimo visits the flamboyant Ratswami. Soon New Mouse City is hit with a series of crimes, and Geronimo is more exhausted than ever. It turns out that Ratswami has given Geronimo a post-hypnotic suggestion and is using the unwitting Geronimo to build a giant hypno-device in the centre of the city with the goal of taking control of the population.
