Jump for Joy!

While cutting through a mountain pass, Ash and friends decide to stop into the local Pokémon Center for directions. Imagine their surprise when they discover it vacated, with no sign of Nurse Joy. The plot thickens when they take it upon themselves to investigate and discover security camera footage of a Shiftry immobilizing Nurse Joy with Stun Spore before carrying her off. Their only clue as to her location is a mysterious entry on Shiftry in the Pokédex, indicating that these Pokémon inhabit only trees that are over a thousand years old.
