Baddy Spawner
A baddy spawner would give players the ability to make custom dungeons in their houses or guild houses. There could be a spawner sold for each different type of baddy. They would have the options to change how often the baddies spawn,
and how many spawn at a given time.

Player Sensors
Whenever a player is near the player sensor, it would activate any conveyor belts/barriers assigned to the same color. It would have an option to only sense yourself, your friends, your spouse, or your guild members.

Mount Sensosr
Similar to the player sensors, mount sensors would activate conveyor belts/barriers of the same color whenever a mount is near.
This could be useful if players want to create mount races inside their house or guild house.

Flag Switch
A flag switch would be exactly like a flag from the tower. However, instead of showing your guild tag when it reaches zero, it would activate any conveyor belts/switches of the same color. These could be used to practice towering tactics,
create unique mini games, or to open a barrier in a custom dungeon.

Ice Blocks
Ice blocks would work exactly like the ones in Box Fort. They would spawn from a certain point, and respawn every so often after being broken, similar to the vases.

Ice Tiles
Ice Tiles would work similar to the tiles found in the event, Ice Race. Whenever a player is standing on top of them, they will start to slip around. These could be used to create unique bush races, mount races, or mazes.
