Has anyone seen Tremors 3 yet? That one is so cool. The Graboids go from worms as we know to shriekers the slog looking creatures and then they turn into something called A** Blasters There basically the slog type but with wings. They build up energy in their A** and then blast off into the sky. It so Oddworld like. Burk is the main character in that one. My favorite Tremors is the first one and the third one.
They remind me of Oddworld too.
