Item description:

The fifth vdeth is the largest of the vdeths. Like the fourth there's a series of relay switches which change the layout of the level slightly when activated. There's a "duel booth" where you try to hit a button before someone else does in order to blow them up, a floaty rocks room, a trap which will only drop you if you look down, a barrel cloning trap, and several other gimmicks and whatnot.
