The "Transformers" Bring Home a Hero DVDs were released yesterday with some special bonus features on the Wal-Mart website.

The code is available inside the Bumblebee and Optimus Prime mask packaging and the transforming Megatron package.

Entering the code "AllSpark62609" at instoresnow.walmart.com will currently net you two exclusive videos presented by the big-box retailer.

The first video is a behind-the-scenes look at the first day of filming of "Transformers: Revenge of the Fallen," which took place at Bethlehem, PA. The video contains quick cuts of various happenings during the first day, along with a funny intro by Director Michael Bay.

The second video is titled "Creating Transformers."

The most interesting part of the first video is that we get a first glimpse of what may be the three custom "hero bikes," built by RetroSBK.

These three bikes looked identical in design except for the colors. One was blue, one purple, and another pink. The motorcycles were ridden by three identically-dressed women.

The bikes in the video differ from the motorcycle that was spotted during the Princeton, NJ shoot.

The motorcycles were rolling head-on to an idle Audi R8, which finally confirms that the R8 was reported on set during the Bethlehem shoot. The supercar does an almost 180-degree spin as the three bikes pass by.

Could these three bikes somehow form to become what many have speculated as Arcee? That is unknown; however, the hue of the purple-colored version looks similar to the concept art that was floating around for Arcee during the production of the original.

What do you think? Is Arcee a possibility?
