Pokemon the Series: Ruby & Sapphire Season 603 Episode 11 Jump for Joy!

While cutting through a mountain pass, Ash and friends decide to stop into the local Pokemon 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 Pokedex, indicating that these Pokemon inhabit only trees that are over a thousand years old. But trees that old don't grow just anywhere! Our heroes find the tree and discover that Shiftry brought Nurse Joy there so she could help a sick Nuzleaf. With some assistance from Brock, the Nuzleaf is restored to health, Nurse Joy is returned to the Pokemon Center, and our heroes continue their journey.
