What should i ask for as a present?

i got really good grades my two semesters last year and the first semester this year. so my mom owes me 3 presents! i guess i can have pretty much anything but im not sure what to ask for. i mean i've always wanted a dog or cat but she says no. so maybe she would say yes to a small pet like a sugar glider or a chinchilla? idk what do you think??? im up for ANY suggestions :)
