The Battling Eevee Brothers

S1, E40: Tracing a path through the woods, the gang comes across a tree with an Eevee tethered to it, next to bowls of food and water. Fearing it’s been abandoned, they look at the collar around its neck and see an address in Stone Town etched into the pendant. Consulting their map, our heroes find that Stone Town is directly in front of them, at the foot of Evolution Mountain. They decide to take Eevee to the address on its collar and find out what’s going on. When they reach the address, they find a huge home with a lavish garden party in full swing, attended by the Trainers of Pokémon that evolve using Evolution stones. Maybe they can find Eevee’s Trainer here?
