Pokémon

I’m playing pokemon blue and just beat Misty, I’ve been having my Sandshrew do a lot of battles in the area and it’s up to lv. 13 now. Is the evolution worth it? Should I just focus on my other pokemon? Does Sandshrew learn any abilities worthwhile or any TMs I can use?

I prefer to avoid using pokemon dbs and to actually learn and expirence the game. I feel like asking on lemmy would be similar to asking your friends at school what todo.

side note: ordered bulbasuar phone case to match my starter :)
