This factory must to be made by LJN. LJN stands for "Laughin' Jokin' Numbnuts." According to The Nerd, the LJN logo depicts all the colors of the 'Shit Rainbow' seen in all of their games and the factory:
Purple: Putrid Gameplay
Blue: Bad Musical Abominations
Green: Graphical Farts and Garlic
Yellow: Piss-poor Lack of Loyalty to Source Material
Orange: Orange (Aren't) You a Fucking Idiot (possibly due to the cartridge art decieving you into believing you're playing an actual ok game)
Red: High Stress Anger Inducing Masochism
Put them together, and you get all the colors of the Shit Rainbow. Hooray, LJN.
