It was a quaint remote that read "Ghostinator" a small thing that selected it's user and turned them incorporeal. It even let the user fly while incorporeal! Henry thought this would work and quickly activated the thing, and quickly found his clothes and the Ghostinator had fallen through his form... or nothing as he was turned incoporeal. He quickly moved through the walls, and found himself in the safe deposit boxes. He grinned as he reached through the metal boxes and then tried to grab what was inside... and then realized a fatal flaw of this plan, and that was the incorporealness than let him phase through the boxes would also not let him grab onto anything.
Quick fix Henry thought as he went back through the wall, and found himself back outside of the bank and reached for the Ghostinator... He tried grabbing it, and then it finally dawned on him that he couldn't grab anything. He was literally just a ghost...
Heist Failure.
