This datapack gives you custom spawn eggs that spawn Christmas decorations on the block you're targeting! The ornaments even sparkle.

On load, a fake player will be created to keep track of the game tick so that ornaments can sparkle at random times. Run function ct_ornaments:give_ornaments to give yourself a stack of each ornament (currently there are eight, more will be added in the future). These are custom spawn eggs, so just right-click on the block you would like to decorate and an invisible armor stand with the ornament will be spawned and placed on that block! Each ornament will sparkle every six seconds, starting on a random tick. If you are not satisfied with the randomization, run function ct_ornaments:randomize_sparkle to reset the sparkle randomization. To remove all ornaments, run function ct_ornaments:remove_ornaments.

Feedback and suggestions are welcome! If you use this in a build or a video, please credit me in the description with a link to the datapack, and I would love it if you sent me a link on Twitter @Danbearpig2 so I can see how people are enjoying my datapacks. I hope you enjoy!
