Empire Strikes Back - Hoth Wampa Cave. The Hoth Wampa Cave was one of five sets produced based on the environments of the ice planet Hoth, making it the most completely explored worlds in the Micro Collection. This set came with five figures including Chewbacca (Drawing Fire), Han Solo (Firing), Hoth Wampa, Luke Skywalker (Prone), and PROBOT (Spy). The playset base has two spots to hang Luke from, one on either side of the cave, and a flick action lever that allows you to help Han Solo and Chewie to watch the PROBOT self-destruct.
