I am a Koala.
"Rute has a very low metabolic rate for a mammal and rests motionless for about 16 to 18 hours a day, sleeping most of that time. Rute spends about three of their five active hours eating. Feeding occurs at any time of day, but usually at night. Rute is an extremely agressive animal when disturbed. It is the only animal on Earth with such a strangely reduced brain."
