Our heroes are on their way to Trovita Island when they come across two Pokemon trainers who seemingly hate each other, even though their two Pokemon are in love. Tony has a male Nidoran and Emily has a female Nidoran and all that the two Pokemon want is to be together. Misty then takes it upon herself to get these two Pokemon together

Ash and the group have finally made their way to the city of Trovitopolis, which has a ferry to Trovita Island, the location of the next Orange League Gym. However, the town is not as normal as they think, apparently a monster is in the sewer and has taken Ash's Bulbasaur. Now Ash, Misty, and Tracey must venture into the sewers to find this so called monster before the city's mayor and his SWAT team close off the sewers and trap them.
