Mega Muck Generations

Mega Mack pouring out of a plant in Sonic Generations.

Mega Mack[1] is a substance in the Sonic the Hedgehog series that first appeared in Sonic the Hedgehog 2. It is a chemical liquid that flows through the Chemical Plant.


The Mega Mack is a pink liquid with texture seemingly identical to that of water. Its properties are inconsistent though. Western materials refer to Mega Mack as a toxic liquid which can poison Sonic in a manner of minutes,[1] while Japanese sources simply refer to it as water with an odd coloring.[2] Regardless, Tails has been unnerved by Mega Mack, hinting it is indeed an unpleasant substance.[3]

In gameplay, the Mega Mack has the properties of water (apart from its color), meaning that the playable characters can drown after being submerged in it for extended periods of time. Contrary to western descriptions though, the playable characters will suffer no form of poisoning from being submerged in Mega Mack.

Game appearances

Sonic the Hedgehog 2

Mega Mack made its first appearance in Sonic the Hedgehog 2. In this game, it is mentioned in Western manuals that Dr. Robotnik flooded the Chemical Plant Zone with Mega Mack to poison Sonic.[1] This is not mentioned in the Japanese manual.

In gameplay, the Mega Mack has no air bubbles in it, so it is easier to drown in. Also, the Chemical Plant Zone boss, Water Eggman, uses Mega Mack as part of his attack pattern. He will fill up his canister with Mega Mack and attempt to dump it on Sonic or Tails. Additionally, the rotating platforms that the battle takes place on will dump the player into the Mega Mack, which will result in an instant death.

Sonic Generations

In the console/PC version of Sonic Generations, Mega Mack appears in the Chemical Plant. It retains all of its properties from Sonic the Hedgehog 2, except that it also contains Air Bubbles.

When Tails is saying that the Chemical Plant looks familiar, he also mentions that the "pink water" makes him nervous. This is a reference to the infamous section in Sonic the Hedgehog 2.

Sonic Mania

In Sonic Mania, with the return of the Chemical Plant Zone, the pools of Mega Mack made a reappearance too. They primarily appear in Act 1.

During the mini boss fight in Act 1 and more regularly in Act 2, there will be pools with hot-boiling Mega Mack that can damage the playable character if they touch it. There are also pools filled with a bouncy cyan chemical, commonly referred to as "jelly".[4] Jelly is a substance that the playable can walk and bounce on when jumping. The height of the bounce is determined by the type of jelly. This is usually required so the player can access higher pathways in the Zone.

Both hot-boiling Mega Mack pools and jelly pools usually have large syringes full of chemicals set on the sides. When the player presses down on these syringes' switches on top, their chemicals get injected into the Mega Mack/jelly. If cyan chemicals get injected into hot-boiling Mega Mack, it changes into cyan jelly. Similarly, there are syringes with green chemicals that can get injected into cyan jelly to change it into green jelly.

In the Sonic the Hedgehog television series, the Mega Mack is referred to as Mega Muck. Also, instead of being a poisonous liquid, it is a glutinous substance which is used to impede Sonic the Hedgehog's movements, similar to super glue.

Sonic the Comic

In the Sonic the Comic series published by Fleetway Editions, Mega Mack is a poisonous substance designed by Dr. Robotnik and another scientist specifically for the purpose of killing Sonic. While toxic in its own right, the Mega Mack will fatally poison Sonic after prolonged exposure.

The second scientist who worked with Robotnik to invent the Mega Mack was caught in a chamber that flooded with Mega Mack, but instead of dying he was transformed into the villain Megatox, whose body is made up entirely of the substance.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Mega Mack is referred to as Mega Muck. Originally, it seemingly had the same properties as the Mega Muck in the Sonic the Hedgehog television. However, its later appearances would depict it as a toxic chemical, like in the games.

After the events of Worlds Collide, the Mega Mack is now seemingly identical to its game counterpart.

Early Sonic canon

Early on in the Sonic series, Mega Mack, also referred to as megamalatricarboSonichloride, was discovered by chance when Dr. Robotnik was fiddling around with chemicals to employ against Sonic, which he marketed as "Mega Mack." The substance was described as extremely lethal, turning anything submerged in it magenta before killing it in less than a minute. However, it was also highly corrosive, disintegrating the barrels for storing it in a few hours. This gave Robotnik the idea of using the Mega Mack to flood the Chemical Plant Zone when Sonic would arrive.[5]
