Koozebanian

The Koozebanians, also called Koozebanian creatures, are sapient beings indigenous to planet Koozebane.

Biology
Koozebanians are smallish beings (they're about as tall as Kermit the Frog). They have two arms but no legs, and a very wide mouth. Their skin is covered in feather/scale-like structures and they have hair on their heads. They display strong sexual dimorphism: females have a long proboscis that is absent on males and babies.

Mating ritual
The Koozebanians' mating ritual is called Galley-oh-hoop-hoop. In the ritual, male and female Koozebanians charge toward each other, howling loudly. When they collide, a large explosion takes place and the creatures seemingly disintegrate, leaving four little babies in their place.

The ritual was reported by Kermit the Frog and indiscreetly presented on The Muppet Show.

Sapience
At first, it might appear that the Koozebanians are non-sapient beings, due to the fact that their mating ritual was reported on TV; Kermit refers to them simply as "male and female Koozebanian creatures" and no technology or intelligent behavior is apparent in the sketch. If anything, the Koozebanians in the sketch display what could be described as uncivilized behavior, acting like caveman (screaming, jumping, running around, strange "dancing").

As it turns out, however, Koozebanians are in fact sapient, and have been observed to use advanced equipment to communicate with their closest galactic neighbors: the peaceful Poobs of planet Poobatron. This probably means that the behavior displayed during the Galley-oh-hoop-hoop mating ritual might be the result of primal instincts; species can be observed in nature wherein death plays a role in their reproduction and the Koozebanians may be no different.
