that sounds like a really dumb explanation and considering Ben knows his aliens by heart and would most likely not how he got Terraspin, I seriously doubt that they're the same. Plus, their powers are different: Terraspin can create a lot of wind, Shellhead can just hide inside his shell (which is why he was given to Kenny, he served for defense, not attack like Terraspin does)
