First Appearance

Chemical X29 is one of Dexter's many inventions, It was used only in the episode "The Big Sister". Chemical X29 is an untested and unstable chemical that can do multiple things to living organisms who consume it.

In the episode Dexter made cookies with Chemical X29 in them. He then tested the chemical laced cookies on two rats and Dee Dee dressed as a rat (by mistake). The chemical laced cookies had different effects on the four subjects who ingested them. One rat shrank, the other grew a second head, Dee Dee grew to giant proportions, and later on Mom was transformed into a hideous green monster with tentacles and one giant eye after eating one of these unsuspecting cookies Dexter had left out in the open.
