This section is still under construction.
The helmet is made from an old baseball helmet and different jar lids. The arm canon is made from different cardboard tubes, plus electronics. The end of the arm canon is held in place with velcro so it can be removed to replace the battery or, optionally, put a speaker inside. Shout-outs to Dave Bell for helping me with the electronics, and to Joe Porsella and Vin Cruz for being my Blues and Roll.
I hope to remake the costume sometime between 2020 and 2022.
