The Icegedunk is a cryptid that lives in Canada and Alaska, supposedly a type of land-dwelling eared pinniped. Facts about breeding behavour and diet and are unknown, due to the fact that sightings are extremely rare, and that the locals say that this remarkable creature is almost extinct.

Description

The Icegedunk seems to be an ottarid pinniped, with a body tapering at the end, but the most remarkable feature of this animal is that it is said to have a fleshy wheel at the end of its body which it uses for locomotion. This amazing feature makes the Icegedunk on of the most bizarre cryptids on Earth.

Doubts about the Wheel

It is said to be impossible for a large animal to have a wheel. Biologists say that it is impossible to supply blood to the wheel, because it rotates. This is why this creature is almost paradoxical, but, since many inventions humanity has made are present in animals-sonar and infared vision for instance, it might not be that big of a stretch to describe an animal with a wheel.
