Transformers: Dark Of The Moon (Wii)
Rock star Bumblebee
Go to the "Last Stand" level as Bumblebee. Then, go to City Blvd. East. You should see a building with a guitar on it. Knock it down and pick it up. It will look like Bumblebee is playing it. Note: This only works with Bumblebee and Barricade.
