Gil has ginger hair shaped in a small toupee similar to his dad, a purple suit with a yellow badge, a white undershirt, a black tie, black shorts, and black shoes with long white socks.
He is much smaller than his dad and most of the students in Cannery High.
Gil respects his dad a lot even though he is aware that his dad doesn't like him. He will do anything to make Mayor Shelbourne proud. However, nothing he does really makes Mayor Shelbourne proud of him (and abuses Gil in return.) Gil is sometimes described as braggy as shown in the episode “My Pop is Tops” in which he brags about the new phone his dad bought for him.
Gil is also seen to keep houses extra tidy as he is so used to taking care of his dad in the episode Poppa Piglet.
- Gil is a new character in Cloudy: the series, along with Old Rick, Hector Evilman, Jim Lockwood, and Brenda.
- In the episode “Flint's Fabulous Future”, when Gil shook the robot's hand, there was no picture of his future, just static. This is a reference to the fact that Gil is not in either of Cloudy with a Chance of Meatballs movies, which apparently take place years after the series. This fact is supported by the fact that Gil states that the static implies that he doesn't even exist in the future.
- Gil is allergic to Banana, Ketchup, Fish and also Oysters.
- In part 2 of the episode "Lobster Claus is Coming to Town", it is revealed that Gil has a very beautiful singing voice. This feat is actually able to make his dad proud of him, though of course it does not last. As when he uses his singing voice again, his dad just tells him "Nobody likes a showoff".
