This is a song sung by Baby Fionna. While in Fionna's mind, Marshall Lee witnesses a memory of Baby Fionna singing this song in the bathroom of Fionna's childhood home. Fionna is not visibly embarrassed about Marshall Lee seeing her singing and dancing as a half-naked baby, but closes the bathroom door regardless.
I'm a tough baby that can dance like a girl.
I can shake-ah my tail, I can do a big twirl.
I'm a tough little baby that can kick all your cans.
Kick all your cans, I can kick all your cans.
If your an evil wizard I will kick for my fans! Hey!
