The American Mastodon is tired. Worn out. Washed up. Used and abused. He needs his rest, and to find a nice, solitary place to be alone. Scientists who study the Mastodon recognize this urge in the animal as natural and healthy. Others claim it makes him "a real pussy".
Either way, the AM will probably be out of commission for a few days. If, during his walkabout, he discovers any large caches of perfectly ripened tubers, or his totem, he'll let you know.
