Where do you relearn moves in Pokemon indigo?

In Pokemon Indigo, you can't relearn moves. This was a feature introduced in later generations.

Here's what you can do in Pokemon Indigo:

* Teach new moves: As your Pokemon level up, they will learn new moves. This is the primary way to learn new attacks.

* Use TMs and HMs: These special items can be used to teach Pokemon specific moves. You can find them in various locations throughout the game.

* Use the Move Tutor: This is a feature introduced in later generations, not available in Indigo.

Unfortunately, if your Pokemon has forgotten a move you want them to know again, you're out of luck in Pokemon Indigo.
