Get ready for the final performance of an ultra cute superstar.
As Ash and co are a mere stone throw away from Mauville City, they soon notice a poster for the House of Tricks. Anyone who navigates this wacky maze will receive a grand prize of a year's supply of Poké-block. Along the way, May meets a cute Jigglypuff, but Ash remembers it all too well. Can anyone listen to its song all the way through?
The gang have nearly arrived to Mauville City, but they see a poster, advertising the "House of Tricks". The winner gets 1 year supply of Pokeblocks. Team Rocket is interested in getting the prize, even the Jigglypuff with the marker. Ash wonders what the competition looks like, but Max is being knocked out by a Whismur. A young trainer appears, scolding Whismur for going away.
The gang introduces themselves and the girl is Alanna. The woman explaines that the host, the King of Tricks will explain everything. The King appears, showing the House of Tricks. The gang seperates - Brock and Max take the right, Ash, his Pikachu, May and Alanna the left way. Team Rocket appear, also splitting in 2 groups.
Jigglypuff follows Ash and others. Ash, May and Alanna have come to a maze. Ash takes a way, but comes to a dead end soon enough. Brock and Max have a dispute where to go. The King of Tricks appears before Ash, May and Allana, mentioing that the doors can be opened, but he stubles upon a sponge room and driftes off. Team Rocket appear before them, and Meowth plans to take Whismur - their boss will know what time it is when Whismur makes sounds.
Ash, May and Alanna have split, going to dead ends. Whismur and Alanna split, but Whismur has been caught by James and Meowth. Alanna tries to find it, with Ash and May helping her. Jessie overhears them and plans to capture Pikachu. As she stalks, Pikachu turns around, so she goes back. Jigglypuff appears before them, singing and making them sleep. When they wake up, May and Alanna laught at one another, but Ash explaines the deal with Jigglypuff.
James and Meowth reunite with Jessie. They have Whismur, but they need to get to Pokeblocks. Ash, May and Alanna reuite with Brock and Max as well. They think Whismur got out so they are going to see at the exit. Max determines that there must be trap doors, so he finds one. The gang have got out of the maze and the King of Tricks is impressed. Team Rocket have got out as well, and while they go, Alanna sees her Whismur found. Alanna thanks them.
Jigglypuff appears once more and sings, makign everyone asleep BUT Whismur. Jigglypuff begins to be angry, but when it sees Whismur not asleep, it is pleased. May and Alanna laugh once more, while the rest is getting their marks off. Whismur hasn't been scribbled on and Max explaines that it is sound-proof. When Team Rocket awake, they are sad they lost the gang. The next challenge is to pass the stream.
The King of Tricks appears again, saying that some of the logs are not safe to pass. The King of Tricks falls into the water, as the log is not safe. Jessie pushes the log, making the gang fall down into water. The next challenge is to choose a correct rope to swing, but if it is a wrong one, the person (which is King of Tricks) bumps into the wall. As they swing, Team Rocket use a mechanical hand to push them, making them fall down.
The next challenge is to climb the rope, but if it is a wrong one, a hammer will smash them down. Just before the end, James appears (dressed) and cuts the rope. The next challenge is to cross the sand without falling into a hole. The Team Rocket is confident to win, as they dig holes all the time. However, when they make their first step, they fall down. Ash is confident that the path is safe, but falls into a pitfall.
The last room seems empty, but Team Rocket appear disguised, making them believe that the last challenge is to jump 10 times the rope and they're done. They do, but the Team Rocket ties them up. They stole Pikachu and Whismur, but Ash sends Corphish. Corphish cuts the ropes, but Jessie sends Seviper and James his Cacnea. Cacnea uses Pin Missile, but is stopped by Corphish's Harden. Corphish uses Crabhammer and knocks Cacnea out. Seviper uses Wrap and wraps Whismur, but Whismur uses Screech, hurting everyone's ears. Whismur uses Super Sonic, freeing itself. Whismur uses Hyper Voice and Corphish uses Crabhammer, blasting them off.
The winner who passed the House of Tricks is Ivan - he recieves the Pokeblocks. May feels a bit bad since Alanna didn't win the prize, with Team Rocket ambushing them, but Alanna thinks it was great when Whismur battled with 'em. Jigglypuff appears once more and sings its song, making everyone asleep. Jigglypuff leaves with everyone having marks on their faces.
