Sometimes the right idea just refuses to spring to mind. I don't remember what I was thinking when I doodled the PPEsaurus, but I imagine I must have been thinking he could have been a mascot for the company's health and safety awareness campaigns. (PPE stands for "personal protective equipment.") I can't explain the hand growing from the tail. I will say that hands are very, very difficult to draw, especially for a terrible artist such as me.
