| The Secret of Kangaskhan
The Secret of Kangaskhan (Japanese: VSガルーラ VS. Garura) is the third round in the Red, Green & Blue chapter of the Pokémon Adventures manga.
Red is in Viridian Forest searching for a Caterpie in a trip advised by Professor Oak to complete the Pokédex. He sees movement in a bush and sends his Poliwhirl to attack, but it's attacked first by a Charmander owned by Blue, who believed that it was a wild Pokémon. Red becomes angry but recognizes the boy that found the phantom Pokémon, Mew. Suddenly, they hear a loud sound and Blue states that he found what he was searching for. A Kangaskhan shows up; Blue doesn't lose any time and attacks it with Charmander. Blue takes out his Pokédex in order to see its information. When Red shows his Pokédex, they realize that they are rivals with the same mission. Red also learns that Blue is the grandson of the famous Professor Oak.
The fire causes a lot of damage to the Kangaskhan and Blue tries to capture her a couple of times with Poké Balls but she rejects them; however, she doesn't attack. Red perceives that something is wrong, stops Charmander's attack, runs to the wild Pokémon and looks to her belly. Her baby Kangaskhan in her pouch was poisoned, so Red utilizes an Antidote to heal it. The mother thanks him and leaves; Blue is mad for Red's intervention and they present themselves "formally." Searching for the same goal, they head on their different paths.
- Blue is revealed to own a Pokédex.
- Red and Blue start their journeys.
