Hi I went inside the PUMA store and I heard this happy song that has a nice tune to it.. but i have no idea what it is called. it goes something like "buh buh buh buh buh buh buhhhh.." over and over again.. i think? hah I know you cant sing it by just reading what i wrote, you need to know the tune... but oh well. im not even sure if thats how it goes but yea.

o yeah and theres another song i think it goes like "sha la la laa.. sha la la la, im with her.. sha la la la" like that over and over again. im not sure tho. haha its just something i think i heard.

if anyone knows, please post! thanks :)
