Mischievous Robot (Alternate Version) - Cave Story

"Mischievous Robot (Alternate Version) - Cave Story" is a high quality rip of the Alternate version of "Mischievous Robot" from Cave Story.

Joke
At 0:24, the leading melody changes to "Battle Field" from Mega Man Battle Network 6, followed by the backing at 0:35.

The rip starts to loop over at 1:00.
