Rotontails are vicious rabbits that make use of wrestling techniques to pummel their opponents into the dirt. They wear a distinctive tiger mask instead of the typical thug's mug found on their pallet swap brethren.
The monster's used of a tiger patterned mask and noted habit of caring for children allude to the titular character of the 1968 manga Tiger Mask, which details the career of a vicious heel wrestler who becomes a face after learning of the negative influence his persona had on the children who idolized him.
