A villain sitting on a mob will begin to spin along with the mob he is sitting on when a creaking is detected.

I found a bug completely by accident. It's a known fact that all villains are afraid of creakings and run away from them. If you summon any raider (for example, a evoker) and mount it on another mob (for example, a creeper) using the command /ride @e[type=minecraft:evoker,limit=1] mount @e[type=minecraft:creeper,limit=1] and then summon a creaking, the evoker will panic and start spinning around with the creeper, although I think the evoker should force the creeper to move away from the creeper when it detects it.
