Silvia Ferreira is the owner of SkyPirate Creations, a producer of custom steampunk clothing and accessories. Perhaps you aren't into that scene. But your guinea pig is and Ferreira has just the rig for it.
Now a question for all of you: who would prevail in a battle between this winged guinea pig and this one protected by full-body metal armor? It's almost a Viper vs. the Mountain scenario. The steampunk guinea pig would have the advantage of speed and maneuverability, whereas the steel-encased guinea pig would have weight and protection.
