Thanks to Sphenicus' efforts, our official resource pack has been updated! If you're using any of the older versions, I recommend getting the new version for various corrections, improvements and surprises.
New to this release are updates to most of the paintings, with new and updated visuals. Plus, a new music track was introduced for the disc that was added in Minecraft 1.16!
For those unfamiliar with the resource pack, it's a light addition to the core game. No blocks or mobs are changed, with the exception of creepers, so the visuals stay intact. The pack focuses on replacing some sounds, music tracks, all paintings, while adding a few surprises true to the Creeper's Lab. Plus, it adds conveniences like a reduced pumpkin blur.
Give it a try! You can download it from the resource pack page.
