Test Tubes (Patreon)

A silly suggestion by a friend that I simply could not ignore. It seemed too silly and cute, and also wound up being a bit naughty hah. Originally meant to just quickly doodle the characters and leave it "loose" but got carried away again and even added a background. It was a lot of fun! I will have to be sure in the future though when visiting this friend to be sure what he means by a "little" help with his experiments!
