Slink

Slink is a fourth grader who is a member of the Tough Customers.

History
Slink was once a student at Mighty Mountain School, as seen in "Buster and the Daredevils" when he and Toby wore Mighty Mountain uniforms during the baseball game.

In his first appearance, "Buster and the Daredevils," he and his "friend" Toby dared Buster to do various dares until he dared them back and turned them against each other. Since then, the two have gone their separate ways, with Slink joining the Tough Customers. He also transferred schools to Lakewood Elementary School.

Physical appearance
Slink is a rabbit with a gray complexion. He wears a gray shirt with a red lightning bolt on the front, long blue jeans and red-and-white sneakers. In his original appearance, his shirt is black, but in all later appearances it is gray. Slink has long dark brown hair that also covers his eyes. His eyes were seen once, in the episode "The Law of the Jungle Gym."

In "To Beat or Not to Beat," Slink is seen in the audience of the school talent show with a darker skin color and lighter brown hair. However, this could just be because of the dimmer lighting of the auditorium for the show.

In "The Good Sport", a miscolored Slink appeared in the audience listening to Mr. Haney's speech. He had blond hair and white skin.

Molly MacDonald
Slink and Molly are good friends, as they are both members of the Tough Customers.

Rattles
Slink and Rattles appear to be very good friends, possibly even best friends.

Binky Barnes
Slink appears to also be friends with Binky.

Toby
Slink and Toby used to be friends, but decided to go their own ways after daring Buster to do different things. It is unknown if they ever became friends again.
