The famous Martian tripod from H. G. Wells' the War of the Worlds. Martian is not removable. Has a base and can be used as a game piece.

Explore the world in your very own Martian Tripod! Blast puny humans with the heat ray, or harvest them in your basket to eat later! Fear an ambush? Just launch a canister of black smoke, which'll choke out the opposition. Knock over trees in your career, wade across lakes, see the world......and FINALLY SINK THE YAMATO!!!

The first one is really just for show. I tried printing it and it wasn't pretty. The second model has the ability to hold smaller minis in its basket, about 28 mm size (I hope). The third is based on the original artwork from the novel. It's more cartoonish.
