Bethany, "Beth", is a cultist in the Rainbow Monkey Cult who kidnapped Numbuh 4 to sacrifice him to the great Rainbow Monkey Kong.

Bethany is a huge fan of Rainbow Monkeys and decided to visit the Rainbow Monkey Fair and Share Fair, a Rainbow Monkeys theme park. Numbuh 3 brought Numbuh 4 there that same day, and Bethany overheard Numbuh 4 yell about Rainbow Monkeys being stupid. Bethany approached Numbuh 3 when Numbuh 4 refused to give her a goodbye hug, which is customary of Rainbow Monkeys. She proceeded to direct Numbuh 4 to a trap when he asked where the exit was located, and transported him onto Rainbow Monkey Island. She and three other cultists chained him up between two pillars and called for the great Rainbow Monkey Kong, which picked him up and carried him into the jungle (Operation: H.U.G.S.).
