Hello there. I've recently purchased from T.R.U. their reissued Insecticons tri-pack. My favorite of the bunch had always been Kickback. I want to know, why do the three Insecticons have a yellow "hatch" on their chest that opens up? What is it for? It's too small for their weapons. Were these Diaclones as well that had a little pilot in them? Would the Diaclone pilot even fit inside the Insecticons chest? Been curious about that since purchase and thought I'd ask you folks. Any suggestions as to why the Insecticons have an opening hatch?
