Farm or animal pen
You should add a farm or animal pen with ACTUAL animals and people can watch them. You do not have to do this if you think the sound is annoying. Also, I once saw a sheep when I ran in the empty fields and it was an actual living Minecraft sheep and turned out the staff helped out by building a pen for it but then after some time it turned out my sheep glitches out because of lag.
We like to keep true to what the actual parks have in them and typically if it doesn't exist IRL it won't exist on the server. So that probably won't happen unless one of the parks adds a Petting Zoo
