This song is from Bucky O'Hare, the game not the show.

This plays during one of the game's most difficult levels, near the end of the game.

This is the second last level.

As you can plainly hear, the song is heavy, yet at the same time there is a sense of urgency to it. Probably to reflect the fact that a single wrong step will cost you another life.

Yay for holes of doom and instant death spikes right?
