A question that has yet to be asked...or at least I think

Would of used the search function but the last time I tried it game me "no results" regardless of what I typed.
Anyway I've heard many questions including:
1. what happened to barricade
2. Why couldn't Jazz be reparied?
3. Wasn't starscream one of the jets in the airstrick against megatron and blackout?
4. How did bumblebee get his voice back?
Those are all very good questions and the answers to all of them are out there. The chat between the 2 writers on the official movie site answered that, but now I have a new question, that I cannot BELIVE hasn't been asked yet:
How the hell did bumblebee get his legs back at the end of the movie? Did anyone else notice in the attack from starscream bumblebee's legs were blown off? Then after the battle's over bumblebee's walking fine again like nothing happened! So seriously how did he get his legs back?
if anything is driving me crazy its not the above 4 questions but that one!
