With the success of the Ghostbusters inspired pack, gun and energy meter, I would like to suggest an item similar to the Ghost Trap (obviously it would be named something different in order to avoid legal issues with the owners of Ghostbusters)

The way I see it, it would have a handle that a minifig can grip, a rectangular box with details to represent the trap itself (which could have the yellow/black stripes painted on it) and the underside would be like the underside of a TLG 1 x 2 tile so it can sit on studs of various kinds.
