Toddy's personality: Smart ass. He has served as both a govt mule and as a battle beast while Marshan was in the Taldan Phalaxers. He has gotten into trouble several times in small towns, and even large ones, so they have agreed for him to play the quiet mule who listens and spies on the unsuspecting peasants instead of walking into town as a talking horse. But once someone has turned their back, a rude comment has a chance of being flung.
body form: Llama. Kind of a camel, kind of a mule, definitely a pack animal, but exotic and weird enough to require DC 15 instead of 10 to identify the animal type. But not a dangerous beast like a small dragon. Just exotic enough to go "what is th..., oh, never mind." Assumed benign enough to never cause a stir in towns until he wants to.
Now, on the other hand, in large, sophisticated societies, he shows his true vocal and opinionated nature. Once he was able to purchase a ticket to the opera in Oppara, but they would not let him in. We spent a few days in jail and a month working off the bill for the damages.
In IC post #43, Toddy was asked to count the number of people who were not visibly shocked by Marshan's spectacle. It would be nice if he could remember their faces, but humans generally all look the same to him.
