Red Bendit's Craftable SlimeBalls

As  already stated in the summary. This mod will let you craft slimeballs with 4 bones, 4 kelp blocks and one kelp. Unlike other similiar mods I have tried to actually make it a bit challenging to get the items needed for a slimeball. I have done this in McCreator and this is my first mod I have done so feedback is appreciated ;). In case you dont know kelp blocks are made out of 9 dried kelp which is made by placing a kelp in a furnace. The reason I made this mod is because I just dont wanna spend 500 years looking for slime chunks. If you have any problems, questions or suggestions for more mods for making something craftable about the mod you can tell me about it in the comments or on my discord NAME: Red Bendit#4239
