October 22 is annual celebration of Wombat Day in Australia. This unofficial observance was introduced in 2005.

Wombats are muscular marsupials, that look like little bears. They are native to Australia and belong to the family Vombatidae. Wombats are the largest mammals, that dig burrows. Most time they spend underground in their extensive burrows and go out in the night. These animals are not commonly seen, but they leave evidence of their passage.
