As before, the main protagonists' faces are hidden. Pikachu, Bulbasaur, Squirtle, Marill, Venonat, and Psyduck pursue Togepi as he plunges into a pit of darkness and ends up in a huge tree that used to be Pikachu's former home.
The Pokémon locate Togepi with the aid of Pikachu's pal Elekid, despite the fact that they were mistaken for an Exeggcute egg. In their search for the lost egg, the Pokémon travel deep inside the tree, where they encounter a group of three dancing bellossom.
As a terrible storm hits the area, Pikachu and his friends try to keep the Exeggcute eggs from being blown away by using moves like Thunderbolt and Water Gun.
With its incredible strength, Snorlax saves everyone with the help of the tree Pokémon. When a Dragonair calms the storm and a Chansey shows up to explain they already had the lost egg, the storm dissipates. Reunited are the eggs.
With the aid of a Leaf Stone, Exeggcute transforms into Exeggutor all of a sudden. In order to return to their trainers, Pikachu and his buddies bid Elekid and the others farewell. In the meantime, Meowth tries to find a campsite in the meantime but becomes lost due to Pikachu's blunders and gives up.
