The Refbot Minibot was one of several minibots released as merchandise. Like the other House Robot Minibots, it was amongst the first run of minbots, released in 2001. It was packaged in a three-pack with Razer and Sergeant Bash, and later in a two-pack with Pussycat.
It is based on the Series 4 version, since he has no counter or card system. The toy's arms do work, however.
