Nicholas Withers is an orange fish. He has blonde hair. He also wears a blue sweater and brown pants.
He is the host of House Fancy, the show where the fanciest houses in Bikini Bottom are shown with the owners. Squilliam Fancyson was originally going to be in the special House Fancy episode Nicholas was hosting, but Nick discovered Squidward's "fancy" house and let Squidward be on the special instead.
- He is nicknamed "Nick". Possibly this nickname came from the Viacom company Nick/Nicklodeon.
