A common bread toaster that Tails the Fox had modified into a DEADLY CANNON.
To quote Tails' own explanation of it:
"The Toaster Cannon, as I have named it, was custom built from a regular toaster. Using technological knowledge, I installed a lazer system into the hull, with an energized crystal core and rechargable chaos batteries. The origional hull was reinforced with a titanium alloy and heat-resistant plating on the inside. It is easilly stored within Hammerspace, and it is a very versatile weapon; effective against most robotic entities, mech joints and weakspots, aliens, and aircraft."
