TFP: Rumble and Frenzy

So apparently if I listen to enough Niki Minaj and have Soundwave in mind, I end up drawing TFP versions of his twerps.

RIBFIR is here.

Here was my intention in the design: Sounders has two for air, two ground scout. Rumble looks similar to a Vehicon partly because that's where Soundwave got the design. I mean, come on, Sounders and Shockie were buddies, so they must've shared information and schematics, rights? Frenzy is obvious. He just looks like a micro-sized Soundwave.
