Squog, as he appears in The Squog Show.
Squog is the prehistoric ancestor of Squidward who appears in Ugh! and The SpongeBob SquarePants Movie IV: The Cloonbob Saga. He also appears in his own spin-off series, The Squog Show.
In The Cloonbob Saga, Squog shows up after Patrick Star-lin drops a basket of tomatoes on SpongeBob. He uses a bazooka launcher grafted to his inner thigh to gun down Star-lin. George Clooney appears out of a time-rift and snaps Squog's neck, killing him.
Squog is the main character of The Squog Show. Set before The Cloonbob Saga, Squog time-travels to the present, only to discover a distopia full of cheesy one-liners and nipples. He vows to defeat the villains responsible for this (however, few episodes move this plot forward).
