tsukiteacups

hi! i'm tsuki, and i just started the game. i had a question. is there any way that you can get the other starters after picking one? say, if you pick torchic, could you get mudkip or chikorita at some point during the game? i was just wondering. i have such a hard time choosing!! (in case you wanted to know, i can't decide between totodile and turtwig. they're my favorites!!!) thanks!!
