Powerful Artist is a song from the Season 4 episode The Painting Gem.
I can create anything with this magical gem
Trace it, outline it, and poof, there it is
Look at me now I'm a master, I'm bright
The best all around
Just watch what I paint
A ginormous throne
Fancy blue shoes
Paint pouring down in such colorful hues
I'm the best I'm a powerful artist
Oh yeah, I'm just getting started
I can create anything
It's all up to me
Yeah, I'm the best
The most powerful artist
