The Squidfather is the big bad and arguably the main antagonist of the first two Freddi Fish games: Freddi Fish and the Case of the Missing Kelp Seeds and Freddi Fish and the Case of the Haunted Schoolhouse. He doesn't actually speak real words; he only grumbles. He is very passive and is seen petting his pet "catfish" (actually a cat with a fish tail for humor). When he gets real upset, he spews ink.
In the first game, he wants Grandma Grouper's treasure chest of kelp seeds so he and his shark minions can grow some kelp. At the end, the sharks tell him they have to share the kelp seeds so all fish can grow kelp because the seeds are for everybody to share.
In the second game, he sends his shark minions to steal toys belonging to the guppies at Freddi's school because he'd never had any toys to play with. At the end, Luther gives him his action figure because he feels that everyone deserves at least one toy.
The Squidfather is an obvious parody of The Godfather.
