Ash and co. arrive at a lakeside. At this time, Ash remembered what Trip showed him with Oshawott’s Aqua Jet in the previous episode. Ash finally has the initiative to train Oshawott. While the group talks about it, they send out most of their pokemon to play. Emolga and Snivy are sent out together and turn their heads in disagreement. Oshawott is sent out last, and Ash tells him that they will be training. The opening is then shown. Iris
is playing with the pokemon Ash is stretching in his underwear as he tells Oshawott to swim in the lake. Oshawott becomes scared when Ash tells him that he will train to open his eyes underwater. Oshawott is reluctant to do so, but does it anyway. Ash has a difficult time breathing underwater. Ash convinces Oshawott to attempt opening diving underwater for a second time. Oshawott’s second time has him closing his eyes even further. Ash forces Oshawott’s eyes to open. Oshawott becomes very anxious and uses Water Gun on Ash, forcing him out of the water.
Iris and Emolga are playing. Emolga sends the ball over to Snivy in spite. Snivy uses Vine Whip and throws it to Dwebble
on accident. Dwebble breaks the ball with its claws on accident. Scraggy
, who is on his own, notices a bunch of Poke Ball shaped mushrooms. Scraggy begins to attack them with Headbutt. Scraggy then sticks his tongue out to taunt the mushrooms. The other pokemon soon notice, and they begin to go towards Scraggy. Cilan just so happens to be preparing lunch after this time. Scraggy and the Foongus
begin to battle. The Foongus stand on one another like a pyramid to poison Scraggy. As the group’s pokemon were approaching Scraggy, they were poisoned too.
Ash and Oshawott are soon aware of the incident themselves. Iris tells Ash about the Foongus, causing Ash to scan them in his PokeDex. The Foongus retreat after that. Cilan goes to his laptop to point to look for the closest Pokemon Center, but there is none in sight. Iris tells Ash that there is a plant that can cure poison. Cilan concludes that it is underwater, but it is stuck between two trenches. In addition, the lake is said to be the territory of wild Palpitoad
. Ash, Cilan, and Oshawott set off to get the plant. Ash and Cilan are wandering in the thick bog as they do so. Ash tells Oshawott to go into the water. Ash puts a breathing mask on and with Oshawott in his palms, he convinces Oshawott to navigate through the water. Ash holds Oshwott, who is still closing his eyes, as they wade through the river. Cilan wishes Oshawott luck. Iris takes care of the group’s pokemon at the moment and she makes a temporary medicine for the pokemon. Pikachu
weakly cries out Ash’s name and hopes he is okay.
As Ash and Oshawott go deeper into the water, an aggressive Palpitoad orders a group of Tymphole to attack them for wandering into the territory. Ash and Oshawott notice the trench where the plant is located. The Tymphole begin to attack Ash and Oshawott. Oshawott refuses to help Ash because he does not want to open his eyes in water. The Tymphole attack Oshawott with Water Gun. Even with his eyes closed, Oshawott somehow dodges all of the attacks. Cilan notices the Water Guns fired out of the water, causing him to worry. The eyecatch and commercials are shown.
Ash wishes Oshawott to do his best, and orders Oshawott to use Razor Shell. Oshawott still cannot attack. By being encouraged, Oshawott opens his eyes slightly. Ash tells Oshawott to open its eyes. The Tympole
launch Bubble attacks. Oshawott finally opens his eyes underwater and effortlessly destroys the bubbles with Razor Shell. This scares the Tympole off. Ash and Oshawott set out to go back to the surface. The angry Palpitoad orders a Stunfisk
, who had been hiding on the ocean floor for quite some time, to attack with its electric-type attacks. Ash and Oshawott are electrocuted, which sends them out of the lake. The Stunfisk arrives on the surface of the water, giggling. Ash scans the Stunfisk into his Poke Dex. Ash and Oshawott begin to wonder how to fight the Stunfisk. Cilan goes for it: He pulls out his lure and goes for “FISHING TIME!!!” Cilan sends out his special Cilan lure. Ash tells Cilan that the rod and lure look cool, but getting the Stunfisk out of the water is what truly matters right now. Cilan guesses the movements of the line based on the ripples that are present on the surface of the water. Cilan’s lure finally gets a hold of the Stunfisk. Cilan pulls the Stunfisk on land.
As soon as this happens, the Palpitoad swims to a lily pad on the surface. The Palpitoad lanches a Ground-type attack and orders the Stunfisk to use the same attack on Cilan. Cilan dodges the attack and tells Oshawott to do his best. Cilan throws the lure at Stunfisk, causing it to circle around in the air. Ash orders Oshawott to battle the Palpitoad now. Ash convinces Oshawott to battle. Oshawott uses Water Gun, but Palpitoad uses Hydro Pump to damage Oshawott instead. Oshawott uses Shell Blade, but Palpitoad uses Hyper Voice to stop Oshawott in its tracks. Palpitoad launches its Ground-type attack now. Ash promises to “get” the Palpitoad. Oshawott uses Aqua Jet, and because of the training, he is able to control the move. Oshawott is unconscious. Ash and Oshawott begin to cheer as they defeated the Palpitoad. Ash uses his Poke Ball on the Palpitoad, and CATCHES IT. Cilan then sends his Poke Ball to catch the Stunfisk. THEY BOTH SUCCEED! Ash’s Poke Ball has a red marker because he has six pokemon on him.
Ash and Oshawott finally have enough confidence to go underwater and retrieve the plant. Iris feeds the plant to the pokemon. They all feel better. Ash and Cilan begin to talk about their two captures, which was all possible because of the Oshawott. Ash and Cilan catch two pokemon and Oshawott masters Aqua Jet.
