Some questions about liquid crystal

Is there a move relearner in this game?
Where is bulbasaur
Where do you get moonstones, and where do you purchase other evolutionary stones?
How do you raise the happiness of a pokemon, and how do you know how happy a pokemon is with you? I'm trying to get umbrion.

Hello! Liquid Crystal is a hack, not an official game. As such, you're better off asking in the hack's dedicated thread: https://www.pokecommunity.com/showthread.php?t=242023

Good luck!
