The hooligans have green skin and dress like punks. They wear indications of their interest in candles, like candle T-shirts and candle tattoos, and wield candles as weapons. They also have an interesting variety of hairstyles (mohawks, cowlicks, spiked hair, a pompadour) that Finn ultimately cuts off with the grass blade.
The hooligans will do evil to facilitate their candle-love, as demonstrated by their choice to rob the elderly and defenseless Suzy and Sue's candle shop. They are belligerent, and when Finn attacks them, they fight back effectively. However, after Finn cuts off their hair, they run away screaming.
