Where is the Score X8 power brick in Lego Batman

The power brick for Score X8 is hidden in the fourth mission of the first villain episode: An Enterprising Theft. You can't get to it during story mode, you have to go back during free play. In the second area, use an explosive on the gate to the left and start collecting colored pieces with the attract suit. In the next room, deposit the pieces into the container to create a small robot. Use the technology suit to direct the robot into the oven at the back wall.
