/spawnseek: Spawns a zombie named Seek. He is immortal and has a pathfinding AI. He can see you anywhere and can noclip over walls. He has Speed 1 and chases after players. After reaching specific coordinates (on his Pathfinding AI) he will stop and return to his original spawnpoint /spawnrush: Spawns a Guardian named Rush. He stands for a few seconds then runs forward very fast for 2 seconds. Sight of a player will insta kill them. Disappears after the 2 seconds of running /spawnscreech: Summons a tiny mob (your choice; has to be hostile) that if you don't look at it in time, it will deal 4 hearts lf damage to you. If you do tho, it will despawn /spawnfigure: Summons a Warden that gets faster depending on how much Books (minecraft:book) everyone has in their inventory /spawnjack: Summons a Skeleton that appears for 1 second and despawns. (No weapon, no ai, include a horror Minecraft sound like the cave sounds)  /spawnambush: Same as rush, but he repeats this process 2-4 times. (RNG how much he comes) /spawnfigure100: Spawns a Warden that has a specific pathfinding AI.
