But barnacles don't have- *checks* "The main sense of barnacles appears to be touch, with the hairs on the limbs being especially sensitive. The adult also has a single eye, although this is probably only capable of sensing the difference between light and dark.†This eye is derived from the primary†naupliar eye." Huh.
It's the impression I got after reading Bob Budiansky's pitch due to implication that Autobots and Decepticons have left Cybertron for the very first time and energon apparently being their only fuel. Doesn't seem to me like it was a sequel to anything.
