A couple YouTube fans (MMPRtoys, BlackNerd, PowerRangersNow, etc.) got the Movie Morpher and Bruno got the Interactive Megazord that had pictures of the individual zords in the back. Here is a comparison of Mastadon (why eight legs?), Sabertooth Tiger, Pterdactyl and Triceratops.
I actually like the Pterdactyl and Triceratops designs. I do not like Mastodon as it looks like a beetle of some kind.
