After winning against Falkner, Ash is psyched about his next Gym Battle, but Brock notices a beautiful girl on the horizon. Soon our heroes spot a Marill but when they try and pick it up, the cry it emits is ear-shattering. Later, after another failed capture attempt by Team Rocket, Ash and Brock get separated from Misty, Pikachu and Marill. Soon the beautiful girl from the horizon charges in and grabs Ash to ask questions about her Marill. She introduces herself as Wilhelmina. A short time later, Brock has a problem: He likes Wilhelmina but if they find Marill he'll never see her again. Will Marill be reunited with Wilhelmina, and what will Brock do once they're reunited?
This is the second of five episodes where Pikachu imitates characters (Four if one dosen't count Dealing with a Fierce Double Ditto Drama).
Wilhelmina is one of the few girls who like Brock back, though he didn't know it, even after she left.
The American version of this episode was the very first of the 21st century.
This is one of the few episodes prior to Chikorita's Big Upset to show Chikorita's jealousy towards Pikachu.
Brock: "My sweet angel is here. She's like a lovely dream come true."
Wilhelmina grabs Ash.
Wilhelmina: "All right you weasely Pokémon thief, what did you do with my little Marill?"
Ash: "Are you supposed to be a dream or a nightmare?"
Wilhelmina shakes Ash.
Wilhelmina: "I heard you talking about my Marill now where is it?"
Ash: "YOUR Marill?"
Wilhelmina: "YES! WHAT HAVE YOU DONE WITH MY Pokémon?!"
Ash: "It... went for a little... swim."
