Minecraft is funny in a surreal way. A TNT explosion of odd themes re-mixed together to generate new experiences that don’t necessarily have any meaning other than to be In The Moment (TM). How else can Spongebob be found worshipped by attentive bunnies in seasonally sensitive, snow covered surroundings!.
P.S. SpongeBob SquarePants for Minecraft is by Spark Universe. The official SpongBob SquarePants page is here but can only be purchased in Minecraft Marketplace (once purchased SpongeBob, and other characters, can be set as a primary game skin in Minecraft’s Dressing Room).
