Hokey Poké Balls (Japanese: フシギダネとフシギダネ！モンスターボールを取り返せ！！ Bulbasaur and Bulbasaur! Regaining the Monster Balls!) is the 34th episode of Pokémon: Advanced Challenge.
The gang arrives at a small town, each one having their own plans. May forgot to bring her Bulbasaur, so it goes out. Ash does not think it is a good idea, but May promised it to look around the town. Bulbasaur goes to eat some fruit at a store, so May stops it, saying one needs to buy, not take it for free. May's friends to at the Pokémon Center, while she goes after Bulbasaur in a truck (which leaves). Ash and Brock charge towards the truck, stopping the truck and getting Bulbasaur back.
Team Rocket works on a machine in the Pokémon Center. Nurse Joy comes to ask when it will be repaired, to which Jessie replies soon enough. It is revealed James worked on the plan for three nights to get it working. The gang arrives - Ash needs to check his Pokémon while Team Rocket leaves, "repairing" the machine. Ash calls Prof. Oak to let him know the situation. Max mentions May caught a Bulbasaur, so she shows it to Oak. Ash wonders how his is, so Oak shows it. Ash thinks it would be best to get Bulbasaur here to show to May's - to play and to know something from one another.
Oak sends Bulbasaur to the Poké Ball, transferring it through the teleporter. Ash calls Bulbasaur, but he does not go out. Some children come to Ash as well, opening Poké Balls and revealing nothing inside. Max thinks that the ones who repaired it messed the machine. Nurse Joy denies the fact, but is convinced when she sees the real repairmen. Team Rocket gets those Pokémon, while the empty ones are distributed. Nurse Joy leads the gang to the back of the Center, so they see Team Rocket stealing the Poké Balls. They fly off, so Ash sends Taillow and May her Beautifly.
James brings rockets to fly off faster. Pikachu uses Thunderbolt, but misses. The rockets break, so Team Rocket are blasted off into the forest. May's Bulbasaur uses Vine Whip to get a lone Poké Ball. Ash's Bulbasaur is brought out, so both Bulbasaur play for a while, but they must get the Poké Balls. Ash demands from Taillow to scour the area for Team Rocket. May orders the same for Beautifly. Team Rocket are seen stashing the Poké Balls and they go away, but James' bag has a hole which drops Poké Balls, leaving a trail. The gang searches for Team Rocket, while May's Bulbasaur goes to sniff a flower. Ash's Bulbasaur goes to clarify May's to search for the Poké Balls. Taillow and Beautifly see the trail of Poké Balls, so they take 2 of them to show to their owners.
Bulbasaurs have found a Nuzleaf and a Shroomish, asking for the Poké Balls, so Shroomish and Nuzleaf show them the way. They lead the gang to the crashed balloon. Bulbasaur sees a Poké Ball - with Taillow and Bautifly dropping the ones they took - to go to get those Poké Balls. Team Rocket are seen to be inside a house to get some stuff. Meowth spots that James' bag is half the size he had before. Jessie notices the hole in the bag. As they go to get the Poké Balls, the gang appears. Team Rocket goes back inside and barricade themselves with steel walls. Ash notices a window is opened, so while May will get in, Pikachu will distract Team Rocket by attacking the wall.
James has another idea - he will use the Pokémon to fight the gang. A Golbat is brought out, tackling Ash. Next, a Primeape is brought, knocking Ash out. Brock goes to help him while the Bulbasaur use Vine Whip to help May and Max go inside. Team Rocket battle the vines, making harder for Bulbasaurs to get the Poké Balls. Brock calls Primeape and Golbat to the Poké Balls. Pikachu uses Iron Tail, destroying a part of the wall, so Team Rocket are surrounded. Jessie sends Seviper and James Cacnea. Seviper uses Poison Tail and Cacnea Pin Missile, hurting May's Bulbasaur. Cancea uses Pin Missile, so May's Bulbasaur uses Razor Leaf, but it couldn't stop the attack. Ash's Bulbasaur uses Vine Whip to negate the attack.
Seviper uses Poison Tail and Cacnea Needle Arm, but are stopped from Bulbasaur's Vine Whip attacks. Bulbasaurs get the last bag, but Team Rocket don't stop yet. Cacnea uses Needle Arm and Seviper Poison Tail, but are stopped by Pikachu's Thunderbolt, blasting Team Rocket off. Back at the Pokémon Center, the gang gives the Poké Balls back to their owners. Oak calls Ash to let him know that at his lab Grass and Water Pokémon fight one another (as Bulbasaur was the one keeping peace). Ash sends Bulbasaur back and leaves the town with his friends.
