The Lemon Sundrop Dandelion is an addictive substance that was used by Renfield T. Rodent and later confiscated by Constable Remington. Overdosing was considered fatal after Mello was killed by the sauce. Because it was addictive, Renfield T. Rodent used the "secret sauce", by putting it on the food, to make his customers constantly return to his amusement park. After Downtown Ebony Hare figured out about Renfield's plans, he forced his way into Renfield's business. After one of Charmy's friends died from an overdose when his hotdog was laced with the substance, the Chaotix came to investigate and arrested Ebony Hare. Renfield was then allowed to operate his amusement park without the sauce, which was confiscated by Constable Remington. (KtE: #13, #14, #15)
