World of Quest is the theme song of the show, and plays at the start of every episode.
The song begins with a musical back-and-forth between Nestor and Quest, before the real singing begins.
Lyrics[]
'N' denotes Nestor and 'Q' denotes Quest
N: My pal Quest does whatever I want
(Too-too-too-too-too-too-too)
Q: Man, I gotta lose this little runt...
(Too-too-too-too-too-too-too)
N: I get to boss him around when we're in a mess
(Too-too-too-too-too-too-too)
Q: This prince Nestor is a royal pest.
(Too-too-too-too-too-too-too)
Save the world! World of Quest!
N: You may be large, but I'm in charge!
Save the world! World of Quest!
Q: Without me, kid, you wouldn't get too far.
Come along, with Nestor and Quest!
To save the world! World of Quest!
Q: I hate theme songs.
