Answer: In the "Christmas Who?" episode's intro, Patchy the Pirate is reading a letter where a fan ask if Spongebob loves Christmas as much as he does. Patchy explains they didn't always celebrate Christmas and this episode is a flashback to the first time Bikini Bottom had heard of Christmas. Santa had never visited before because nobody had believed in him before. Santa finally does visit because of Squidward's Christmas spirit. The "It's a Spongebob Christmas" episode aired 12 years later. So by this time, Bikini Bottom had been celebrating Christmas for quite sometime. Santa comes for a special visit because of how everyone in town, except Plankton, is on his naughty list.
