Mole Missile
From Multiversal Omnipedia
A one-time inclusion in the Swat Kats' arsenal, the Mole Missile was a non-explosive, narrow missile whose tip produced wide, spinning propeller-like blades. It was used to drill a hole in the side of Dark Kat's volcano lair.
A more advanced version of the Mole Missile was a diamond-tipped drilling missile used in the Swat Kats' unsuccessful attempt to pierce the armored hull of a Macrobot.
