Not on MY Watch Ya Don't! (Japanese: ポケッチ入手困難！？ Can't Get the Pokétch!?) is the 10th episode of Pokémon: Diamond and Pearl.
Ash and co. finally arrive at Jubilife City, the first stop in Dawn's quest to be a great coordinator. It is there that she learns of a new fad. It's hip, it's hot, it's happenin' it's the Pokétch and, like all girls, Dawn has to have one. She gets one from three clowns only to find out from a smart little boy named Landis that it is a fake. Will she be able to get a real Pokétch, or will she be a trend loser?
Coordinators are already training their Pokémon. Dawn is also prepared to go, as well as Buneary and Piplup. However, Dawn, Ash and Brock wander through the town. Dawn wants a Pokétch, something Ash does not know what it is. They see an advertisement of it - the Pokétch is a small piece of tech to keep a person informed. Dawn wants it, as any Coordinator must have this. However, Dawn is being told inside the store that the producer took all the Pokétches away as they contained glitches. Dawn is depressed and Brock proposes a lunch.
Suddenly, they see some traders, dressed as clowns. The audience wants the Pokétches and Dawn comes. The clowns are Team Rocket and they plan to steal the Pokémon, so they give her the Pokétch. They also give it to Brock and Ash, though they don't need one. As they get on the devices, the heroes see a Shinx. Its owner comes to tell that the Pokétches are fake. He says that the Pokétches are fake because of their color - he takes Dawn's (much to her disapproval) and sprays water, only to reveal that the color faded away. He knew about this because his father wouldn't make something like that.
Inside the factory, the boy's father apologizes for his son's behavior. The heroes tell that he caused no trouble at all. The man knows about the fake ones and he took the Pokétches away. The boy is told Dawn is the newest Coordinator and tells she's a rookie. The man wants to test something - a prototype. It measures the friendliness between the person and the Pokémon. The man tests Ash and Pikachu, revealing a powerful bond between them. He then tests Brock and his Croagunk and sees a bond between them, even if Croagunk is Brock's newest Pokémon he got. Lastly, the man tests Piplup and Dawn. Dawn and Piplup are shocked to see the bond between them is weak.
The boy recommends Dawn not to enter the Contest. Dawn wants to see the bond between him and Shinx, but the boy refuses, as he is attending the Trainers' school. He wants to enter the Sinnoh League when he ends the education. Ash tells they will be rivals if that happens. The man tells Jenny is investigating the case and the boy wishes Dawn luck at the contest - "as she will need all the good luck she can get". At the Pokémon Center, Dawn is furious and wants to prove him wrong. Suddenly, Pikachu sees something - a group of Pokémon are wandering out. The man got a fake Pokétch and analyzes it. A voice of Psyduck is heard and Shinx gets out. The heroes see that the Pokémon go somewhere and meet the man and the boy.
It is a Psyduck who calls the Pokémon and Team Rocket alter its voice so that the Pokémon come into the cage... hypnotized. Meowth gives Psyduck a basket of fruit as an reward. The heroes come and the boy goes to get Shinx. Suddenly, the cage's door falls down, almost hurting the boy, but Dawn took him out of there. Landis, the boy, is now fine, while Team Rocket appear on the cage. The balloon forms itself and Team Rocket departs. Pikachu goes to use Thunderbolt and Piplup BubbleBeam, but they got trapped. Dawn sends Buneary, who uses Ice Beam, but they are too far away. Dawn and Buneary make a bond and Buneary uses Ice Beam at maximum power, freezing Team Rocket.
The engines fall down and Pikachu and Piplup are released. Ash sends Starly, who gets Piplup. However, Pikachu falls down and Ash goes to get him, but too late - Pikachu is injured. The cage falls down and the Pokémon gain their consciousness back. The Pokémon go to their trainers, including Shinx, who goes back to Landis. Team Rocket unfreeze themselves and are furious. Jessie sends Seviper and James his Carnivine. Seviper uses Poison Tail and Carnivine goes to bite, but get countered by Peck and Dizzy Punch. Landis' father orders Shinx to use Spark on Pikachu, so Pikachu's power is restored and blasts them off Thunderbolt.
Jenny and Joy come to see what happened and help. Brock flirts with them and gets jabbed by Croagunk. Landis thanks Dawn for the rescue and marks her abilities. Next day, Dawn gets the Pokétch she longed for. Now, Dawn has now her primary goal in mind - to win the Jubilife City Contest.
Marina, the female choice from Pokémon Crystal who appeared in The Legend of Thunder, appears on a Pokétch advertisement in a different outfit.
