The Wickersham Brothers

The Wickershams are a family of apes from Russia on The Wubbulous World of Dr. Seuss. They are based on the Wickersham Brothers, who are described as "jungle monkeys" in the 1954 Dr. Seuss book Horton Hears a Who!
On the series, Wickersham Brothers play various minor parts, often as servants, delivery guys, or sidekicks to Jane Kangaroo and Yertle the Turtle.
