Graalians - Halloween Ideas

So I was thinking we could have some sort of costumes for baddies dressed as zombie and zombie pirates for york in the cave!

And I was thinking we could have a some of challenge where you enter a room like the archery thing, and you're alone with 4 more people in a room where zombie baddies constantly spawns and we can have some sort of reward if the team gets this much zombies killed and you can make the zombie shoot fire and have obstacles and bushes where zombies jump from idk just an idea! But obviously it would be hard like there would be a lot of zombies and stuff! Just an idea.
