Badger! Badger! Badger!
Badgers are tough little animals. They can run up to 30 km/hour (20 mph) and have been known to fight of animals as large as bears (!). They're found throughout Europe, Asia, North America, and Africa.
I haven't seen references to South American badgers. Has anyone seen one in South America?
