There are some easter eggs by renaming some items in an anvil/computer! (For example, try renaming the Cardboard Cutout to "Herobrine", or the Smile Drawing to "perplexed". If you want you just have to check out the "items" folder in the pack to see all the items with alternate textures when you rename them, but I'd have some fun trying to find a couple beforehand!

Some of these textures are on different blocks in the 1.20.1 version, as is with previous updates. Check out the 1.20.1 changelog to know what those are.
