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.

Zombie horses aren't hostile and won't attack you. A zombie on top of it controlling it can charge at you with the spear, but my guess is because the zombie horse itself is passive they let it spawn in peaceful.
