Stefano is a huge amphibious vehicle who can transport engines and other vehicles around the world. He is a bit of a showboat and loves to wow people with his amphibious ability, and revels in their surprise. He is a confident performer and raconteur who likes to tell stories and sees himself as a boat of the world. Stefano can be quite charming and gentle and is not really as full of himself as his pompous manner might suggest. There is a genuine warmth to his larger-than-life, friendly personality, and he truly cares about others.
