Kip and Biederman

Kip O'Donnell and Neil Biederman are the evil poachers in The Wild Thornberrys.

Plot
Kip is often shown to be Nigel's enemy (then more of Eliza's foe). Kip is almost always shown with Neil Bedierman whose stupidity often frustrates him and is shown to be a very tall man in "Matadi or Bust" because he dwarfs Nigel, who, in Happy Campers is revealed to be 6'2. Kip is at least 6'8. Kip is almost always seen dressed in camouflage grab, a matching sun hat, one wooden peg leg, one boot,and round frame sunglasses. He is bald, but has a British style mustache. Kip speaks in a deep, rasping voice with almost an Australian accent.

In "Koality and Kuantity", Kip said he grew up in Sydney, Australia. Kip is assumed to be the same age as Nigel, because, in "Matadi or Bust" it is revealed they used to know each other. Beiderman is almost always shown with Kip O' Donnell. Physically, Beiderman is a heavyset, somewhat short man. Beiderman appears to be slightly younger than his friend, Kip. Beiderman has styled brown hair, and almost always wears a green military outfit, black boots, and rectangle-framed sunglasses. He speaks in a high-pitched, silly sounding voice.
