Eternally optimistic and completely lacking in sense, he can be called "curiosity in human form."  With or without permission from his Master, he will often leave to indulge in the pleasures of the world.  He greatly enjoys being inflated like a balloon, whether using an air tank, a pump, or simply via the Command Seal of his Master.  He does what he pleases without regret.  His conversations, through no ill intent on his part, have a way of meandering toward maximum social awkwardness.
