It has to pertain to video games. I found the perfect theme for you while I was listening to SSBB.
Metroid Prime - Samus' Theme Song sounds VERY similar to the menu theme from SSBM (I never played metroid nor SSBM before sadly). Use that to transition those themes together. You can skip around and experiment with different themes. Doesn't have to be Metroid all the way and that's it for that.
