The itsjim adds well jim. Jim is a famous youtuber with 200k subscribers and i added him to minecraft.
The jim mod might actually affect your game alot like this adds jim cages which is made out of barriers, and bedrock meaning with some unbreakable block breaking glitches you could make something interesting, and jim spawns in the jim cages, and jim drops a nuke wich is 4 times better than tnt. Jim can also fly, and yes he is a cow.
