Hey man, why's my fur, like, pyschedelic?....animal facts (2)

Koala bears only spend about 4 hours a day awake. There are over 900 different kinds of eucalyptus tree in Australia of which koalas will only eat between 8-40. So you could say they are fussy eaters. But there is apparently something in the eucalyptus trees they do eat that causes a drug like/hallucinogenic effect on them. So basically, koalas can only be awake for 4 hours a day as they are permanently stoned.
