Our heroes are wandering through the forest without a compass, trying to find the path to [[Vermilion City]]. [[Ash Ketchum|Ash} and [[Misty]] are fighting, as usual, this time over who led them astray, while [[Brock]] is trying to get them to cool down.
They pause for a rest, and Ash sees an [[Oddish (Pokémon)|Oddish]] taking a drink. Misty sends her [[Misty's Starmie|Starmie]] to fight the Oddish so she can catch it. The Oddish is defeated, but Misty's [[Poké ball]] is deflected by the appearance of a [[Bulbasaur (Pokémon)|Bulbasaur]] before she can claim it. The Bulbasaur attacks and defeats the Starmie; Ash sends his [[Ash's Butterfree|Butterfree]]
The trio attempt to cross a rope bridge, but a wind starts to rip the bridge apart. Brock falls into the river below, while Misty and Pikachu cling to Ash. Ash ultimately manages to pull them up, and the three make their way to the end of the bridge. They make their way down to water level and go looking for Brock. At once, Misty falls through a deadfall into a pit. Ash pulls her out, and they go on looking. As they walk along, Misty's toe catches a rope, and they find themselves suspended in a net. They're found by the Bulbasaur.
Brock and Ash are tending to a [[Staryu (Pokémon)|Staryu]], while Misty apologizes to the Oddish. She and Ash begin quarrelling, and the Bulbasaur tackles Misty, thinking Oddish was in danger. Melanie explains that Bulbasaur volunteered to protect the whole village. Bulbasaur tries to push Ash out of the village because it doesn't trust Pokémon trainers. Ash wishes he had a Pokémon that brave.
Team Rocket appears from behind a cloud, standing on a balloon-lifted platform, reciting their mantra. They land in a clearing outside the village, and try to collect all the Pokémon in the village with a massive vacuum. Brock herds everyone into the cabin, but Oddish gets caught in the suction. Bulbasaur rescues Oddish with its [[vine whip (move)|vine whip]]s, and Ash helps block the wind so it can carry Oddish to the cabin. The vacuum starts to actually pull the roof off the cabin, so Bulbasaur uses its vine whips to smack the hose around. Ash releases his [[Ash's Pidgeot|
Melanie asks Ash to take the Bulbasaur with him; the village is too small for its bulb to grow. She says the Pokémon are staying in the village too long, because the Bulbasaur has done too good a job of protecting them. She feels Ash will be a good trainer for Bulbasaur. Bulbasaur agrees to go with Ash, on condition that they battle first. Ash sends Pikachu, and the two trade rams. Bulbasaur uses its vine whips to toss Pikachu around, but Ash calls for a [[Thunderbolt (move)|Thunderbolt]], which shocks Bulbasaur into submission, allowing Ash to catch it in a Poké ball. Brock offers to stay and help, but Melanie refuses, telling him to continue on his adventures.
