Eggpod/Eggmobile/Egg-O-Matic, whatever you want to call it.
I busted out laughing in issue 230 when Eggman's hovercraft pulled out several hands and blasters (including a slingshot). Gotta say, that Egg Pod is one sweet ride, It can fly pretty damn fast and high in the air, you can attach it to various robots and other things like flame throwers, drills, submarines, plus it can transform into a walker, or monster truck.
All the cool villains need hovercrafts, whether it be Eggmans Egg Pod, Bowsers Koopa Clown Car, or Dr. Wily's various Skull faced U.F.O's.
Where can I get a cool hovercraft to mock my friends with XD
