Snout is just so... aimless. He doesn't really have any goal. He just goes with the flow.

Put a scrap of paper with part of a text in front of him? Okay, he'll go on a quest.

Put a naked lady in front of him? Okay, he'll have sex.

Put a box of food in front of him? Okay, he'll devour all its content.

He's only ever reacting. Never acting.
