This is the Power Tread, a firetruck looking Mutant Machine! But what's a Mutant Machine? Basically just a very flexible car toy, also feel free to check out my first post on Mutant Machines here! I think this is my favorite Mutant Machines vehicle so far because it looks like a really cool and mean looking firetruck, take a look at its windshields and you'll know what I mean. You wouldn't want to mess with this car/creature!
