This resource pack brings back the old minecraft spawn eggs from before they were retextured to be differentiatable, but adds the heads of the mobs they spawn to the corners of them so you can differentiate them! While I personally much prefer the new spawn eggs introduced my mojang, for those who don't this pack could be a great alternative!
I got the whole idea for the pack many years ago from the scratch game Paper Minecraft by Griffpatch on Scratch, a great game btw, but when I checked if there was a pack that added spawn eggs of this style to the game, I was shocked to find there wasnt one, so I planned to make it myself, then mojang retextured the spawn eggs. I eventually still made the pack but yeah I do think the current vanilla ones look much better than any variation of the old ones, but if you asked past me, a pack like this would have been the perfect solution, so if anyone still likes the old spawn eggs but wants to use differentiate them, thats basically why this pack exists :D.
