Isn't this the Worm from the 2nd trailer that Link fights with the flame thrower? It looks like from the 2nd image that they are designed to blend in with their environment as well. Their bodies resemble rocks, and so if they were hanging upside or stuck on the side of walls as it looks like by their suction cup feet, I think they will jump out at us. What has me excited is look at all the different colors they come in, so if they are ment to blend in with their environment, that's 10 different underground, cave or dungeon area environments right there.
