I do some searching and have found this carrot mod it basically spawns in a whole dimention that is made out of carrot blocks it seems like a very fun mod. Also i think we should get the necromancy mod it pretty much has like body parts that you find like cow and squid and all mobs and you can take them and combine them into a freeky creature i think this would also be a fun mod a lot would enjoy if you can't find these mods id be happy to post a link to them thanks for reading.
