The Intergalactic Massage Convulsions

The Intergalactic Massage Convulsions, or the I.M.Cs were a serious of bizarre natural events which created many of the characters. There have only been two I.M.Cs in the history of the universe.

Creation
The universe's walls are made of solid diamond. When the universe grows to big, the diamond walls send a shock wave through it to make it the right size again. Of course this causes multiple issues for the many planets.

Effect on Earth
When the convulsions hit Earth, they sent shockwaves through the planet's core which mutated several people. Some of the people who took the worst of it were:

First Convulsion

 * Changer
 * Security
 * The Bearded Ape
 * Amphibians

Second Convulsion

 * Mutant Lizards
 * Muppety Puppety
 * Hello
 * Hokey Pokey

Of course there were many more, but that list is for another day.
