Pulguinha the Steampunk Guinea Pig doesn't need a jetpack, because he has a pair of brass and leather wings, perfect for soaring high among the airships.
Pulguinha's winged harness is the work of SkyPirate Creations. You can see more of their work (and more Pulguinha) on Facebook or purchase some of their steampunk goodies for humans through Rebels Market, Storenvy, and Etsy. We can only hope that the motor on Pulguinha's back means that the wings actually flap, even if he can't quite fly.
