Jiggle Billy was first seen in Dumber Dolls as a toy Meatwad wanted Frylock to buy for him. His $149.95 price tag (apparently having something to do with his expensive night vision goggles - for night jiggling!) caused Frylock to buy Meatwad Happy Time Harry instead, whose nihilistic, suicidal demeanor and surly attitude eventually made Meatwad depressed and bitter, prompting Frylock to splurge and buy Jiggle Billy in an attempt to improve Meatwad's attitude. By this point, it's already too late, as Happy Time Harry promptly begins mocking and berating Jiggle Billy, making him depressed too, forcing him to admit he doesn't know why [he] has these goggles and culminating in him shooting his head off with his blunderbuss in a suicide attempt, which he survives apparently no worse for the experience except for still being real depressed.
