Initials

When you start your Pokémon journey, you can instantly find 3 Pokémon: Bulbasaur, Charmander, and Squirtle. Click on one of them and choose your favorite. You can only take 1 of them.

But there is a technique: you can pick up a Pikachu as an initial. For this, you must run from the initials 4 times and the fifth time, the Pikachu will appear.
