Sketch of a new power up

This is a my sketch of a new possible power up, a false brick.

The idea is got from Mario Kart 64, from the false square power up. The power up holdes the place of the back-floating barrel.

This is its behavior: a car (car 1) release the false brick, another car (car 2) behind goes at full speed and gets the brick, but the car 2 remains surprised, because in the moment that the car 2 takes the brick, it explodes thaking car 2 flying.
