Ash, Pikachu, Brock, May and Max decide to cool off in a picturesque lake en route to Rustboro City. But they're not the only one's splashing around! The lake is actually home to a whole flock of Lotad. The Lotad seem to be having fun with their new friends, but a little girl named Natalie thinks that Ash and crew are out of line. She brings them back to the flower shop which her two older sisters run. There, Ash and the gang learn all about berries and the effects that different berries have on Pokémon. Brock promptly falls in love with the two older sisters, making little Natalie very jealous. In fact, Natalie isn't the only one smitten with Brock—a quirky little Lotad seems to have taken a liking to him as well. Natalie decides to win Brock's affection by finding a Sitrus Berry and she wanders off into the woods. She finds one, but a Beedrill wants it, too! Luckily, Brock arrives in time to save her from the Beedrill. Meanwhile, Team Rocket has decided to catch all the Lotad in the lake and it's up to Brock's quirky Lotad friend and Pikachu to save the day.
