So this is what happened on AJ's server last night.
Jaslo spawned giant zombies inside AJ's pyramid, then she, Toxic, and I started firing flame arrows at them (you have to aim very precisely since their hitbox is their crotch xD) to kill them. Then Sev joins in the fun too. ^^
I don't think AJ was very happy about it (since we also spawned the Wither as well and had to kill it before it destroyed everything
Then it just turned into a mass-spawning of chickens and I decided to spawn some ocelots as well.
