Alice was getting annoyed with Arlo every time he tried to pop in for a drink. I think he's getting to big for the pouch.
Red kangaroos are found in groups called "mobs" which can number over 1,000 animals in areas where forage is good. Although they tend to conserve energy during the heat of the day, they are capable of moving at great speed. Kangaroos can cruise for long distances at 30mph due to their efficient hopping, which uses less energy and requires less effort by the kangaroo than running would. They are so well designed for hopping that they can't move their legs independently in a typical walking motion, and cannot walk backwards at all. (philadelphiazoo.org)
