I didn't really like the last theme song I made, so here's a better version:
I want to be a great adventurer, like no one ever was.
To slay evil is my real test,
To kiss Princesses is my cause,
I will travel across Ooo,
Adventuring far and wide,
For each evil-doer to understand,
The power that's inside!
Eating apple pie for eternity!
You're my best friend!
In this land we must defend,
A heart so true,
Our righteousness with pull us through!
Every trial along the way,
With mathematical-ness I shall face,
I will adventure every day,
To claim my righteous place.
You high-five me and I'll high-five you!
Got to lump 'em all, got to lump 'em all!
