Pokémon (1997)

S6E39 A Poké-BLOCK Party

While Ash and his friends are just a short distance from Mauville City, they come across a poster advertising the House of Tricks. It promises a fantastic reward of a year's worth of Pokéblock for those who can make it through the quirky maze. During their adventure, May encounters an adorable Jigglypuff, but Ash and Brock recall their past experiences with the creature. The question remains: Can anyone withstand listening to its lullaby until the very end?
