I play on a server, and it has a bunch of plugins, but i got some parrots and they wont get off. Ive tried dying, leaving,sleeping, even /kill and /effect, also /killall. I want them off bc its hard to sneak up on people with 2 parrots screaming around, like an alarm. What do i do? Btw i am not the owner, but i do have op.
