Squilliam Fancyson is the arch-nemesis of Squidward Tentacles. Everything Squidward has failed at, Squilliam has succeeded. Squidward is painfully jealous of him and constantly attempts to show Squilliam he's not a loser, with varying results. Squilliam first appears in the season two episode "Band Geeks." He was voiced by Dee Bradley Baker, who also voiced Kevin C. Cucumber, Perch Perkins, and Bubble Bass.
Like most octopuses on the show, Squilliam has six tentacles and shares a similar design to Squidward all around. Squilliam has a large black unibrow which he takes special pride in and wears a fancy maroon colored robe.
