Captain Pud is a
Captain Pud is Newton's father. Unlike Nana Pud, Newton's mom, Captain Pud actually looks like Newton. He has a light bulb head, just like Newton, but he has a mustache on the outside of the light bulb and a Lizard-thing on his head and is worn like a hat.
He is mentioned in the Prologue that he made Newton's Airship, and it appears Newton really likes his Father. He also is mentioned before Newton releases the Titans, that he said that Newton should never open the lid. He makes his first appearance after the last Titan is defeated.
