The centerpiece of The Ocean Disaster book is Dr. Cosmic’s latest invention, a submarine shaped like a giant squid. He calls it the SKWID, which stands for “Scientific Kinetic Waterproof Investigation Device.” (Dr. Cosmic likes to make things complicated.)

I began by researching what a real giant squid looks like and collected lots of photos and notes. I learned about how squids move and what their various parts are for. Then I tried to put myself in Dr. Cosmic’s shoes. If I were to design a submarine based on these amazing creatures, what would it look like?

To help me visualize this crazy invention, I decided to build 3D model that I could use for reference. I build my models with an app called Sketchup, which is pretty easy to learn and even has a version you can use for free.

I also researched real submarines in order to draw Dr. Cosmic’s blueprints showing how the SKWID actually works.

Building the model took a long time, but once it was finished it made drawing the SKWID so much easier. Using the model, I could get a better sense of perspective and lighting, which helped make the illustrations feel more realistic.
