Every item in your ModKit must work with the same version of Minecraft.
Your ModKit contains items and you selected a Rainbow Lucky Block ModKit.
Play the Rainbow Lucky Block challenge on a map based on Mario Kart 8 on the Nintendo 64! Race against another player to see who can destroy all of the Rainbow Lucky Blocks on their side of the track first! Defy gravity as you navigate the track sideways and upside down around loops and turns. Each Rainbow Lucky Block you destroy holds a suprise that can either help or haunt you. Good luck! You will need it!
