The client ask for a mascot monster to represent the dangers of the red dye 40. It causes problems in teeth, besides hyperactivity and aggressiveness.
Kids usually don´t really like to be call "babies", once they feel that they are grown up, but the effects of the Red Dye 40 seems to make them like babies: Hyperactivity, bad humor, trouble concentrating, that´s why I represent those problems in this monster, and add the diapers.
It has little feet and hands so the kids don´t see him as a threat (diapers also help), even with the big mouth and rotten teeth.
