Found these at a Walmart in Plano, TX (Ohio St. @ SH 121). I recognize one of them as an Optimus Prime mold (ID'd as Cybertron Prime by Runamuck--thanks!). The difference? One has a shovel/backhoe arm (left) and the other a loader arm (right). Here's the Prime mold.
Looks like the commonplace over-sized Legends Cyb Prime & Hotshot KOs, not familiar with Dinosaur or Constructo though.
I remember my cousin got one of those a couple of years ago, and had the dinosaur one. I have no interest in them myself, especially since their sold at Walmart (I don't shop there whatsoever anymore).
'I'm getting prehistoric on yo ass.' We never get deals like that here. That said, I own the original figures already, and have a 'DinoCock Prime', and think those t-shirts wouldn't suit me anyway (or be in my size).
