Energon Megatron Questions

Disclaimer:
I searched this forum up to several pages to make sure my question hasn't been asked lately. I tried to use the search function, but nothing would come up. Not even the search word 'Starscream'.
Note:
This post talks about unboxing an Energon Megatron. If that makes you cry, it might be best to stop reading now.
I bought a boxed Energon Megatron off of e-Bay a few weeks ago and finally got him in to battle my husband's Unicron. While I was carefully taking him out so I wouldn't lose any accessories, I noted that there were two sets of four flat rectangular pieces of clear plastic taped to the bottom of the box. I looked at all the instructions and all of the pictures on the box. There isn't an explanation as to what to do with them anywhere.
At first my husband and I thought that maybe they were Make-It-Yourself Energon Cubes. Using a some tape and a lot of effort, I managed to get four of the pieces together. They are NOT Make-It-Yourself Energon Cubes as they don't have any side squares that would fit. That and they look wobbly and rather drunk.
Next, I went to the Energon Megatron toy gallery here on Seibertron to see if they were pictured as part of the picture gallery. While flipping through the pictures, I noticed that they not only show that Sword-that-is-also-a-tank sword that Megatron comes with but also an Energon Axe/Sword!
I KNOW my Megatron didn't come with any really cool Energon Axe/Sword that he can hold in his hand! So I race back to my flat rectangular pieces of green plastic to see if THEY turn into a cool Energon Axe/Sword. They do not.
So here is the point of my long and rambling post. Does anyone know what those flat rectangular clear green pieces of plastic are? And where in the world do I get my Megatron a really cool Energon Axe/Sword? Thank you for any help!
