For years explorers have wanted to solve the mystery of the Abominable Snowman.
Now a team of Russian and American scientists are setting off to try and find the hairy creatures, which are also known as Yetis.
There's been a rise in sightings of the unknown animals in the Kemerovo region, which is east of Moscow.

Experts have argued about whether such a creature could live in The Himalayas and Siberia.
The mysterious animal is rumoured to be the size of a human but is hairy like a monkey.
Ore has been looking into it.
