The Threatening Bears are two bears hand puppets that appeared on the short-lived ABC TV comedy program The Sideshow. They are very aggressive and always hurt their friends. The most common "friend" to appear is the Koala who is most often hurt. Another friend who commonly appears is a Kangaroo, who sometimes wears a moustache (in this case he is known as a "program supevisor"). Other friends to appear are a sheep, a cockatoo, and The Election Worm.
These hand puppets are usually operated by The Umbilical Brothers, and have their own small segments between certain "show breaks".
A comic has recently been created for the Threatening Bears by Jason Weibel with the approval of The Umbilical Brothers.
