Doesn the Flying Slig in the Abes Exoddus opening have flapping/vibrating wings?
Yes, indeed he did, although neither that Slig nor his flying harness exist today. The propeller flying harness model, which we see throughout the rest of the game, was found to be cheaper to manufacture, and so the old model was put out of commission. Unfortunately for that particular Slig, the smell he could detect was ozone, created by burning lubricating oil. Within ten seconds of him leaving the screen, his wings seized up, causing him to crash in a spectacular fireball.
