While most of the smaller Pokémon are taking a nap, Togepi suddenly wakes up and, after seeing a group of flying Pokémon, finds itself separated from the rest of the Pokémon. Noticing this, Pikachu, Bulbasaur, Squirtle, Venonat, Marill, and Psyduck go in search of Togepi. It is there that they meet Elekid, who leads them to a group of Exeggcute. However, one such Exeggcute has a missing egg, and believes Togepi to be their missing part. Thus, the gang must travel to find the missing egg, and endure a storm that could blow Togepi and the Exeggcute away.
