Undead mini-boss that summons regular undead mobs

Wouldn't you like to see a mob that spawns on specific nights (like on full moon for example) and summons a few of undead mobs (packs) around them? This would bring some difficulty to full moon nights and encourage players into developing a bit more strategy when fighting undead mobs. I suggest that this mob should have different variants throughout the different biomes, just as regular undead, but with slightly desaturated colors and being a bit taller than their regular variants. • More health points and damage (×2 of his regular undead variant). • Unique drops- you name it (I suggest a rare chance of dropping a golden apple). These mini-bosses are smarter than regular undead and can sometimes (only while unattacked or not recieving damage) hide between their summoned undead pack to heal up little health for a short time. Any suggestions? Vote for this feature if u liked it please, I'd really appreciate it! Thanks for your attention :D *PS: Remember this would be different to the "Leader Zombie" mechanic from Minecraft Java, which is not implemented to Minecraft Bedrock. My post is a reimagined version of said mechanic, intended to be implemented in both Java AND Bedrock editions.**
