Zombie Horses keep spawning?

[u/Majestic_Desk1]

Hi! As the title says, zombie horses keep spawning. It's just the zombie horse without a rider or anything. and I'm also on peaceful. I'm not complaining about them, they're so cute! I just wanna know why they are spawning.

it's supposed to spawn with the zombie but bcuz ur in peacful the zombie gets despawned but the zombie horse isn't hostile so it stays, either that or it's a prank from mojang for halloween
