Missy loves to play chase outside. It’s not fair for us humans, though. The outdoor enclosure is built into a hillside, so while Missy just runs from one side to the other on flat ground, we humans have to run up a hill, around the back side, and back down again. Meanwhile, we can hear Missy laughing in anticipation of our arrival. When we finally get there, Missy has already taken off again.
As fun as it is for us to play chase with the chimps, we much prefer when they play together.
