Dinghy Dog
From Monkey Island wiki
Dinghy Dog is a henchman of LeChuck's who works as an entertainer at the Carnival of the Damned (the Big Whoop Amusement Park). He is a parody of costumed entertainers at amusement parks.
His only appearance is in The Curse of Monkey Island. He wears a giant yellow dog costume with a sailor hat and runs a booth where he guesses the weight and age of guests, with the guest winning a prize if Dinghy Dog guesses wrong. Available prizes include a small anchor and Murray the talking skull. Guybrush will lose if he asks Dinghy Dog to guess his weight, but he can win by having him guess his age because LeChuck has cursed him into the form of a child (Dinghy Dog guesses seven years old) but his SCUMM Actors' Guild card proves that he is twenty.
Dinghy Dog displays a very condescending attitude towards children and treats Guybrush very disrespectfully. If Guybrush shoves him several times he will pick Guybrush up in his (dog's) mouth and bite him.
A doll of Dinghy Dog can be found on Plunder Island inside the Massive, Man-Eating Snake. What happens to Dinghy Dog after LeChuck's demise and the destruction of the park is unknown.
