Koalas
Australia has had a record heat wave, resulting in devastating fires.
Koalas, if you don't know, are not social and don't come out of trees or into the suburbs very often. Reason being, under normal circumstances, they don't usually drink water in the normal manner. All their food and water requirements are provided from the eucalyptus leaves that they eat. That's why they sleep about 22 hours of the day because the calories and liquid intake is not enough to keep them awake all day long, however, they consume enormous amounts of leaves in that time.
The following photos are even more amazing once that fact is known.
