Need ideas for Birthday magnet for DCL door on cruise.

[FigmentSpark]

My sister (over 40) is having her birthday while we're on our cruise. On top of that, it's St Patrick's day and and excursion day. I'm trying to think of a neat design to help celebrate her birthday. I have some St. Patrick's Mickey clipart, as well as some birthday Mickey clipart, but I'm at a loss as to what to do with them. So I need some ideas.

My door will already have some Mickey head designs for the cruise, and the porthole will have a captain's hat. In addition, we have a few other small things, so there will be space for something.

I was at first thinking of doing a special Mickey head for her with a birthday theme, but I thought it might get lost amid the others on the door. Then I thought of changing our porthold captain's hat to a green tophat with candles, but that seemed cheesy. So now I'm left with a small banner with "Happy Birthday sandwiched between Mickey and Minnie. It just doesn't seem enough and I don't know what kind of background to put in.

This is what I have so far:



I could maybe put it on a scroll shape, but it needs to be grounded. What background would I use or at least, what kind of "floor" would I give them?

I also found this clipart, but I'm not sure how I want to use it:


Any ideas would be really appreciated. I'm drawing a blank.
