type Casting (ウソッキーはどこにいる！？ Where is Sudowoodo!?) is the 5th episode of Pokémon: Johto League Champions.
On their way to Ecruteak City, Ash and co. are dismayed that the bridge will be out for six months. They encounter a fisherman who says he'll take them across the river if they can catch a Sudowoodo. While trying to find one, the heroes encounter two arguing scientists named Pierre and Marie. They are fighting over what type Sudowoodo is. Who is more right, and why does Sudowoodo have a fear of water?
As the heroes wander, they come to a river. They go downstream and encounter some workers. They ask where they can go across a bridge, while the man tells them that a typhoon destroyed all the bridges, but his team will build the bridge in six months, shocking the heroes for that statement. Team Rocket travel in the balloon and are about to cross the river. James uses the balloon fire to cook potatoes and they light the fire even more. However, it burns away the balloon before they cross the river and fall down. The heroes encounter a fisherman and ask him to carry them across the river in his boat. The fisherman asks them a favor: to catch a Sudowoodo and if they do, they will get transported. The heroes go to get it, while Team Rocket plan to give it to the boss.
The heroes begin their search in the dense forest, while Psyduck comes out and is told it can help search Sudowoodo. It travels a bit and spots a Sudowoodo, imitating a tree. Psyduck tries to keep pace, but Sudowoodo confuses it. Psyduck comes back to Misty and points at Sudowoodo. Misty tells they are not looking for trees, but seeing Sudowoodo move, she detects it. Sudowoodo moves away, running off from the heroes. The heroes encounter two scientists, who argues about who is smarter. The heroes come and introduce themselves, while the scientists are Pierre and Marie, all who try to find Sudowoodo. Pierre tells they were discussing that Sudowoodo is a Rock-type Pokémon. Misty and Ash find it hard to believe, since Sudowoodo looks more like a Grass-type Pokémon. Marie confirms it is a Rock-type Pokémon, but tells Pierre thinks the experts who claim this fact are wrong, since Sudowoodo was seen using a Fire-type move. Brock tries to do research on position of love, but Misty pulls him as he is left out.
Ash sends Noctowl to search for Sudowoodo. Marie tells that Sudowoodo were seen with many branches, making Ash to think they are Grass-type Pokémon, but drops the fact when he hears from Pierre they gather branches to look like it. Noctowl found Sudowoodo, so Ash calls it back and sends Chikorita. Suddenly, they see Sudowoodo using Vine Whip, but they see that it must've picked a vine from the forest. Sudowoodo uses Razor Leaf, but also see it collected dried leaves. Chikorita uses Vine Whip, hitting Sudowoodo, but Sudowoodo uses the same move to hit her, so everyone has a thought Sudowoodo is a Grass Pokémon. Ash calls Chikorita back and sends Totodile. Totodile uses Tackle, but misses. Totodile uses Water Gun, but Sudowoodo dodges. Totodile goes to use Bite, but chases Sudowoodo down, causing it to fall in a hole. The heroes think that Sudowoodo is a Ground-type since it used Dig, but see Team Rocket captured it. Using Smokescreen, Weezing covers the field with smoke, causing Team Rocket to disappear. Marie sees that they won't know what Sudowoodo's type is, so Brock tells he will leave his friends and dedicate his life to find out, only to be bashed by Misty for that statement.
Meowth asks what type Sudowoodo is. James thinks it is a Grass type by its looks, though Wobbuffet comes out and talks with Sudowoodo. Meowth asks Sudowoodo what type it is, but gets the answer it is the type that wants to eat. Jessie gets angry, but Sudowoodo is still hungry, so they decide to get it to the old man and get going. They come to the old man, who has doubts that is Sudowoodo, since it does not say anything. He notices it does not look healthy, so James uses a Squirtbottle to water it. However, Sudowoodo gets scared and runs away, so Team Rocket and the old man chase it. The heroes search for Sudowoodo and see it on a rock. Sudowoodo runs away, so Brock tackles it and licks to calm it down. He gives it food, so Sudowoodo wants more of it. With that, they go to the lab and go to analyze Sudowoodo. However, they see Sudowoodo cannot use Vine Whip. Ash's Pikachu uses ThunderShock to get it to use Vine Whip, but are all surprised Sudowoodo used ThunderShock as well. Pierre discovered that Sudowoodo can use Mimic, to they all understand Sudowoodo is copying attacks after they are used.
Ash knows it does not prove that it is a Rock-type, but Marie sees a way they can prove it. Pierre goes to prove it is a Rock-type by splashing water. Sudowoodo, scared of water, runs away. Ash chases it and encounters Team Rocket and the old man. Marie asks the old man why is he here, as he is her grandpa, who was asking to find Sudowoodo to have Marie test it, since she wanted that. Team Rocket still want Sudowoodo for their purposes, as Jessie sends Arbok, while Ash his Cyndaquil. Arbok goes to tackle Cyndaquil, but gets slammed by Sudowoodo's Slam. Sudowoodo distracts Arbok, then uses Faint Attack to stomp on Arbok, followed by a Low Kick. Jessie calls Arbok back and sees it uses sneaky attacks, which fits into Team Rocket's ranks. Wobbuffet comes out, so Jessie sends it to battle. Ash's Cyndaquil goes to use Flamethrower on him, but Sudowoodo intercepts and, via Mimic, uses Flamethrower. Jessie recognizes its value, so tells Wobbuffet to prepare himself. Cyndaquil uses Tackle, but gets blocked by Wobbuffet's Counter. Misty sends Poliwhirl and tells Ash to attack Wobbuffet for a second. Cyndaquil uses Flamethrower, so Wobbuffet prepares to use Counter. However, Poliwhirl uses Water Gun, pushing him and Team Rocket away which results to them getting blasted off.
The water sprays, so Sudowoodo runs away. Marie tells them to stop chasing Sudowoodo, since now she has the clear facts and knows Sudowoodo is a Rock-type, since it runs away from water. Pierre admits that they wouldn't have been convinced if they did not see that for themselves. Pierre and Marie promise each other to focus on the facts and not to prove a point. For helping out, the old man carries the heroes in his boat across the river. Team Rocket climb a cliff and James grabs a branch. The Sudowoodo has this branch, which it releases, causing Team Rocket to fall down.
