Parrots are supposed to imitate skeleton horses, endermen and zombified piglins as they imitate all monsters, they however, don’t imitate them.
Steps to Reproduce:
Have parrots near skeleton horses, endermen and zombified piglins, they won’t imitate them.
Expected result:
Parrots should imitate all three of them.
Actual result:
The parrots did not imitate them.
i think its because zombie piglins and endermen are neutral,while skeleton horse is passive.
