Mummfied mob/mobs

Please Minecraft we need mummfied mobs in the game, I love playing the game and I am against duplication glitches/mechanics. A mummified mob that exclusively spawns at the desert temple (like how the witch spawns at its witch's hut) and drops sand would definitely address this broken game glitch/mechanic issue, that being end portal sand dupping. It would give the desert temples more value or could even create its own structure.
