Not to be confused with Mummy (Overworld Life Mod).
The mummy is a hostile mob that spawns in desert temples, it is functionally very similar to a zombie in its stats and its behavior towards players, golems, and villagers, but it does not burn in sunlight nor spawn in baby/villager variations, and they never spawn with any tool other than a golden sword.
Uniquely, if lit on fire by walking into fire/lava, being hit with a fireball, or being hit with a flaming arrow, the mummy's body will be engulfed in flames for a moment before its cloth wrappings are burned away leaving a Charred Zombie.
Mummies drop rotten flesh and gold nuggets upon death, much like zombie pigmen.
