The SpongeBob Mobs Mod brings some of the characters in the SpongeBob SquarePants universe known as Bikini Bottom to Minecraft Pocket Edition. Some of the characters include SpongeBob himself, Mr. Krabs and Sandy. All of the characters can be spawned using one of the spawn eggs which can be found in your creative inventory.
They can only spawn by using a spawn egg. It’s mainly just a fun addition to the game for anyone who enjoy the TV show and want to experience some of it Minecraft.
