Our heroes are camped out by a lake where Ash wakes up one morning and sees a Rhydon emerging from the water. A swimming Rock-type Pokémon seems impossible, but one of the local Rhydon has indeed learned to use Surf—and a girl named Pietra is out to catch it! She's trying to complete a tunnel to a nearby town, but Rock-type Pokémon flee the excavation site whenever water drips from the tunnel's ceiling. If she had that swimming Rhydon, though, it would keep digging the tunnel no matter what!

Ash and his friends offer to help, of course. After chasing a wrong lead or two, they catch up with Rhydon in the middle of the lake. Pietra asks Rhydon to battle her, but Rhydon couldn't care less; it learned to swim so it could reach an island full of apple trees, and right now those seem much more interesting. Just as they catch up with Rhydon again, Team Rocket descends from the skies, grabs Rhydon, and flies away. They don't get far before Ash and his friends stop their escape, free Rhydon, and send them packing.

Rhydon just wants to leave, but Pietra clings to it and demands a battle. She refuses to let go even when Rhydon dives below the water, so it takes her to shore before walking away. Pietra pleads for Rhydon's help one last time and Rhydon finally agrees to battle, though it takes some hard work on Marill's part to weaken it so Pietra can make a capture. With Rhydon's help, the excavation is soon complete. Ash and his friends exit the newly completed tunnel and continue on towards Olivine City!


Ash and his friends are camping out by a lake where Ash sees a Rhydon swimming around the water. A Rock-type Pokémon that loves swimming is unheard of until a local girl named Pietra confirms what Ash saw as a swimming Rhydon. She is hoping to catch it to complete a tunnel for her grandma to allow her easier access to the nearby town, but all of her Rock-type Pokémon flee from the tunnel whenever water hits them from leaks in the ceiling. Pietra thinks that if she could catch the swimming Rhydon then it could help her complete it.

Ash, Misty, and Brock offer to help Pietra catch the Rhydon. After finding out enough about the Rhydon they find it swimming towards the center of the island in the lake. Pietra gets ready to battle Rhydon, but Rhydon ignores her and continues to swim toward the island in the center full of apple trees. When they find Rhydon again, Team Rocket come in and try to steal Rhydon, but as usual Ash and his friends stop them.

Rhydon starts to leave, but Pietra clings to it until it battles her. Rhydon ends up going underwater to try and shake her but she doesn't let go, sensing her determination, Rhydon takes her to shore before leaving. Pietra starts to beg Rhydon for a battle and finally Rhydon agrees. Using only her Marill, Pietra captures Rhydon. With Rhydon's help, Pietra soon completes the tunnel. Ash and his friends exit the newly completed tunnel and continue on their way to Olivine City.

Who's That Pokémon?

Who's That Pokémon?: Sunflora (US and international), Rhydon (Japan)


  • When Wobbuffet pops out of its Poké Ball while Team Rocket is talking about capturing the Rhydon, Jessie says that it is too bad they can't just make a trade. This is most likely a reference to the fact that she received Wobbuffet from a trade.
  • This episode marks the first use of Iron Tail in the anime. Iron Tail would go on to be one of the most commonly used attacks in the series, known by over fifty separate Pokémon as the anime has progressed (with one of the Pokémon knowing the move being Ash's Pikachu).
  • This episode is possibly a reference to the Surfing Rhydon that appeared in the Generation II games in Ecruteak City.
