Suggestions for prom?

My girlfriend asked me to sadies in kind of a cool way so I need to kind of do the same. The way she asked me was I got a stuffed animal frog each period and 2nd period I got a little message saying: "Out of all the frogs in the lake, you're the prince I want to take." And later in my 4th period I got a little puzzle and when i put it together it said "Will you go to homecoming with me? - (her name)" So.. I was thinking I'd go along with the frog thing and say something like "Out of all the princesses I could choose, You're the one I could never refuse. Your little frog's still in need of a kiss, to turn from a frog to a handsome prince." We've been goin out for about 2 weeks now. Any suggestions about something else I could do going along with that? I walk home with her occasionally, we dont have any cles together, uhh thanks for answerin.
