Whiplash

Although Redmond (the rabbit) and Spanx (the weasel) are two animals chained together, the gameplay is much like any other platformer. The player controls only Spanx, using Redmond as a weapon or tool as the situation requires. Spanx has most standard platforming abilities, while Redmond is completely indestructible as a result of tests conducted upon him and so can be hurled into security guards, jammed into machinery, and used as a grappling hook, among other uses. Redmond can be inserted into special outlets to be set on fire, frozen, or become radioactive.
