Mega Muck

Mega-Muck is a super-sticky substance created by Doctor Robotnik. The ingredients are one part petroleum, one part quicksand and one part clay mud. Robotnik used it in some episodes of both seasons in the SatAM series. In the episode "Sonic Conversion", after reverting to his evil robotic personality, Uncle Chuck made a batch of mega-muck to lureSonic into a trap after kidnapping Tails and Antoine.

Archie Comics
Robotnik used Mega-Muck in an attempt to capture Sonic in the pilot issue of the Sonic the Hedgehog miniseries.

Mega-Muck made a reappearance in Sonic the Hedgehog #228 when Sonic, Tails,Antoine, and Rotor (called Boomer in the Issue) were in Chemical Plant Zone. Mega-Muck came out of a hatch in the ceiling and the group made a hasty escape out the room. In this appearance Mega-Muck is purple. Tails identifies Mega-Muck as "Viscous polymer with toxic properties". Given the properties of Mega-Muck in this story, it seems to be based on Mega Mack in other continuities.

Mega-Muck would later reappear while Sonic, Tails, and Mega Man went through aSpecial Stage half-pipe during the Sonic the Hedgehog and Mega Man comic crossover event, Worlds Collide. Surrounding the Mega-Muck was a desert and several robots from the Mega Man universe. (WC #8)
