I suspect they were aiming for "bullet", rather than "snail" (as in "Metal Slug"). Anyway, as I said, I think old media is covered fine, which is why "Spasma", "Slag", etc can all be used In the original shows. In Beast Wars, they say it out in frustration. If they said it to Black Arachnia or Airrazor directly, then there would be a problem. I just think that Hasbro are being cautious from this point onwards. It's got to start at some point, after all.
