I know they've made quite a few, but none of them allow you to travel to Bikini Bottom. So what this mod should do is, of course add the SpongeBob characters as mobs, but also add in new dimensions as well. The first dimension is Bikini Bottom.
To get there, you need to craft a sponge wand. To craft it, you need one yellow wool block on the top middle, two sticks below it, and black wool on the bottom left and bottom right, then you just right click, and it creates a pineapple block portal, which you jump through, and you're off to Bikini Bottom. The main block you'll find is sand, you'll find grass in Jellyfish fields though. You can always craft a jellyfish net, using these two recipes. For the net head, you need eight sticks, and one string, for the handle, just three sticks. Then stick the head and the handle in a crafting table, and you've got a net! Then you can catch jellyfish, and let them go by right clicking on them. Don't attack them though, because then they'll become aggressive. You can also obtain a jelly bucket by right clicking on the jellyfish. And you can eat the jelly. There's also some new ore: money ore, ketchup ore, mustard ore, and mayonnaise ore. The condiment ore will turn into condiment packets when smelted. As for the money ore, you can mine money from it, though be careful of the cave dwellers when mining. With the money, yoy can buy Krabby Patties by right clicking on Squidwards, SpongeBobs, or Mr. Krabses. Or you can just kill Mr. Krabs, and use the formula to craft the Krabby Patty. You can also get Krabby Patties, and the Krabby Patty formula as a drop off Plankton, either that or chum. Chum is edible, but it has the same effect as rotten flesh, and will even poison you! Hostile mobs include Plankton, Flatts, Karen, The Tattletale Stranger, and other SpongeBob antagonists. Even the Hash-Slinging Slasher, which spawns at night, and burns in the sunlight. Other dimensions include Rock Bottom, which you need coal blocks to make the portal, and using the sponge wand. There's also the freezer, which you just enter the freezer door to get to, where you'll find frozen Krabby Patty ore, which you can mine with a pickaxe, the place is full of jelliens though. Once you coom the Krabby patty in a furnace, you'll need some buns. Just place the patty in a crafting table with beard, and you've got your patty. You can also add condiments to it, by adding the packets to the patty in a crafting recipe. It'll still be a Krabby Patty, only it also lists what condiments are on it. I don't have time to go over the rest of it, it's pretty late.
