A question to US Customs

I've recently been wondering how do some characters cross the border with United States. In light of the following questions in the customs form:

Are you bringing with you:

a. fruits, plants, food, or insects?
b. meats, animals, or animal/wildlife products?
c. disease agents, cell cultures, or snails?
d. soil or have you visited a farm/ranch/pasture outside the United States?

There is no way whatsoever that a creature like this

will be allowed. So how come he gets to speak (regularly) at UN when he is so obviosly:

• Infested by insects
• A prime example of wildlife
• A cross between a disease agent and a cell culture
• Containing lots of soil embedded in his unwashed exterior
