Im playing pokemon diamond and i caught a budew. it evolves with friendship during the day. i looked it up and Roselia learns some good moves around levels 15-20, and my budew is level 22. my question is when my budew does evolve, is it going to learn all those moves it should have learned all at once, or will it not ever learn them, all help is gladly appreacited :) Slim Select Keto
