Burrito is pretty irresistible. He also tends to be a bit shy at times. When he is feeling playful he will often initiate play with his caregivers by biting on a toy or a firehouse as he shyly looks in our direction. If he is feeling particularly playful he will add a foot stomp and a head nod in for good measure. One of my favorite moments is when I go out to the greenhouse to see what the chimps are up to and upon first sight, Burrito grabs something to bite on, stomps his foot at me and takes off running for a game of chase, laughing all the way.
