The Invention Cabinet is a small cabinet that can be seen outside the Gadget Room in Mission's 1-11. The cabinet only has 3 metal gates locking away some of G's failed designs, except for the Solar-Powered Flashlight which actually worked. The only known purpose for the Invention Cabinet, is that Gary the Gadget Guy probably ran out of space in the Gadget Room. In Mission 7 you have to use the secret code to unlock the gate which is holding the Electromagnet 2000. The invention cabinet was destroyed in the Popcorn Explosion.
