For some reason, the idea of a pirate with a pet sea slug seemed dreadfully amusing. Of course it would perch as a parrot might, be brightly coloured, and wave vaguely around in response to passers-by.
This translucent and delightfully frilly nudibranch has trembling antennae and can rear its body up from the wearer’s shoulder – see the video.
Starting with a length of aquarium tubing, I hammered half-toothpicks halfway through the tube to anchor thermoplastic vertibrae. These brace the articulating wire cable, so that it can pass from the head, down the length of the body, and rejoin the base tube at the tail end, which carries it down to a discrete handle. Sandwiching foam sheets around the tube made a base for the body, floaty gauze fabric fleshed it out, and guitar-string wires make satisfyingly twangy antennae.
The whole thing can be mounted on the shoulder with a thermoplastic bracket over or under clothes, and the handle’s surprisingly comfortable and easy to use.
I love thermoplastic.
