As a Pokémon expert, I can guide you through the process of evolving a Bellsprout into a Weepinbell, and then into a Vileplume in the Pokémon games.

To evolve a Bellsprout into a Weepinbell, you need to gain enough experience points (EXP) through battles or other means of gaining EXP until it reaches level 21. Once it reaches this level, it will automatically evolve into a Weepinbell.

To further evolve a Weepinbell into a Vileplume, it requires a different method. Weepinbell evolves into Vileplume when exposed to a Leaf Stone. In the games, you can find a Leaf Stone or purchase one from a specific in-game location, and then use it on your Weepinbell to make it evolve.

Here's the step-by-step guide:


1. Catch a Bellsprout or evolve one from a Bulbasaur if you have one.

2. Gain EXP for your Bellsprout by battling other Pokémon or using other methods like using an Exp. Candy.
3. Level up your Bellsprout until it reaches level 21 to evolve it into a Weepinbell.

4. Find or purchase a Leaf Stone in the game.

5. Use the Leaf Stone on your Weepinbell to evolve it into a Vileplume.
