The group enters Hop Hop Hop Town just as children are disappearing in the town. They go to the Pokémon Center and notice the Pokémon are not feeling well. Officer Jenny soon picks up sleep waves on her radio. They track the source to a huge mansion on the top of a building where inside a Hypno and a Drowzee are sitting on a table. The people there have been using Hypno as a sleep aid and this has been generating sleep waves that was sapping the energy of the Pokémon in the center. Misty takes a look and starts acting like a Seel. Misty leaves the building and runs to a remote forest area where all the missing children were hypnotized into thinking they were Pokémon. They use Drowzee to reverse the hypnotism and also notice it wakes up Pikachu. They take Drowzee to the Pokémon Center and the Pokémon recover too, all except for a Psyduck. Psyduck keeps following them and when Misty falls, a Pokéball rolls towards it. Psyduck gets in and becomes Misty’s newest Pokémon, although she wished it had not.
