Let's not dwell on the past. Things happened as they happened, you have a kid and you don't want to sing the damned Happy Birthday song yet another year. Boy oh boy do we have the cake plate for you.
With the push of a button, the Musical Cake (and pizza) Tray will play Happy Birthday (so you can sit in awkward silence while the plate does your job for you). But what's just as handy is that a series of LEDs illuminate around the cake's perimeter, signaling where the 12 slices should go.
