You're trying to tell us that 18 hours of sleep still wasn't enough? Golly-gosh, koalas might be the squeest lazy bums ever!
You'd hug a tree and love it too, if you needed to sleep an average of 17-hours-a-day and there wasn't a bed in sight!
"My what floofy ears you have Mr. Koala!"
"The better to hear your squees with, my dear."
