I have always believed this to be the case, much as Eye Beam = Optikk from the NA.
Likewise, shortly before Snout Spout appeared on the market, a German magazine ran a create-a-character contest, one of the winners of which was a warrior with a human body and an elephant head. And a gentleman e-mailed me a while back claiming that he created the character of Mosquitor as part of the same create-a-character contest that Fearless Photog won. His character was not one of the winning entries yet shortly afterwards he saw his character on the shelves. He told me his Dad attempted to take legal action against Mattel but was unable to.
