I was fiddling with RTS Grapple and realized that if you look at him backwards and set the crane up off the back, it could potentially be retconned into a Sludge, esp if you turn his head around and set his arms up backwards like in an Ultra Magnus custom I saw. It got me wondering-what other toys out there would make for a "quick" Dinobot? and by quick i mean a color change and dino parts, no major adjustments to the transformation itself.
