Yeah, Mexico is known for Pinatas (Hm... how do I put the tilde in?) too, so they kinda spread into the US that way
Oh of course! Hehe, yes Mexico would have them! ^_^
Oh, the "ñ". In Spain, its actually a letter - eñe, and it figures on our keyboards (...ghjklñ) which is why sometimes, when I make silly typos, an ñ appears every now and then.
But to make an "ñ" you just hit:
Alt Gr + 4 which is ~ (unless this is different on other keyboards, but I don't think so) and then you press n, and - ñ
