Toybreaker Brick

This is a cleanup block. Anything the game files as a toy, glowsticks, footballs, beach balls, kites, golf balls, the little remote control cars and drones, disappears the instant it touches the brick and goes straight back into the inventory of whoever threw it. Nothing is destroyed, so there is no cost to letting it eat your stuff.

The obvious spots are the boundary of a golf course, the floor of an arena where spent glowsticks pile up, and any shared build where somebody keeps leaving litter everywhere. One line of it along an edge is enough. It is Cyborg stock, so it turns up very late, well after most players have stopped caring about clutter.

The line stamped on it is the internet stock phrase for a person enforcing joyless rules, which is exactly the job the block does.
