From Homestar Runner Wiki
Professor Experimento, played by Pom Pom, is the super genius, rocket scientist and formula specialist in Dangeresque 3: The Criminal Projective. He apparently got Dangeresque kicked out of the space program in 1983 over some unidentified event involving a plastic bag of scorpions, back in Dangeresque 0: The Prequel Begins. Dangeresque claims that it was because Experimento stole his design for a rocket that runs on tomato soup, which resulted in the manufacturing of the Ruby Powered Rocket.
Despite this, Experimento is more than happy to remake Cutesy Buttons' rainforest formula. In return, Dangeresque returns the Ruby Powered Rocket's launch codes and ruby, which he steals back from Perducci and Sultry Buttons, respectively. Whether or not Professor Experimento and Dangeresque become friends again is still undecided.
