The experience amount when killing Zombie/Skeleton Horses, Zombie Nautiluses and Camel Husks is inconsistent with other monsters, they all drop 1-3 experience orbs, this is not consistent with other monsters/undead mobs, which normally drop 5 experience drops.
Steps to reproduce the issue:
Summon any of the above mentioned mobs, kill them
Expected result:
They should drop 5 experience orbs as they are undead/monsters
Actual result:
They drop 1-3 experience orbs as if they are regular passive mobs
Can confirm, but this behavior makes a lot of sense to me, these mobs aren’t really “monsters” in that they don’t commonly attack players directly.
