Not sure if it's been discussed before as I haven't watched all the video reviews, but I found what I think are Stealth Force modes for DOTM DLX Bumblebee & Sideswipe. Those modes don't appear anywhere in the instructions. BUMBLEBEE Those pieces under the roof, they're shaped like cannons and have no function in robot mode. Stealth Force mode (with cannons deployed) SIDESWIPE See the tab holes under the front bumper in front of the wheels? They serve no function in car or robot mode. If you fold out the arms, you'll notice tabs on the forearms. Stealth Force mode (with blades deployed) Similarly, Crankcase's pincers are overlooked in the instructions but they're clearly meant to be used as weapons in vehicle mode. Same with Roadbuster's weapons on the back of the car. I wouldn't be surprised if more DOTM toys had hidden Stealth Force modes.
