You Can Bank On Batman: The Power Brick is hidden on the left side of the
cage that Clayface stands on.
An Icy Reception: In the building behind the catwalk after you find the
ice cream on the floor, you must glide to the Power Brick from where you
built the grappling grab spot. You will also need to do it in Free Play mode
because you need someone who has super strength such as Clayface or Mr.
Two-Face Chase: The Power Brick is hidden in the final stage of the level
where you fight Two-Face. It is in the top left corner of the park on the
left, behind some explosive barrels.
Riddler Makes A Withdrawal: Build a car out of the pieces of the neon
light on the side of one of the buildings after you come out of the
elevator. Take the car to the area where you build the wrecking ball. In the
top right corner is a car compacter. Roll the car in there, then mind
control the person to pull the second lever. Note: This must be done
in Free Play mode.
On The Rocks: In the first room after you go inside, freeze all of the
ice cream floats, and go across them. Do not mind control the person and
raise the level. At the end of the floats is an iron gate. Blow it open, and
go inside. Go up the ladder and down to where the hanging bars are located.
Break the crates, build the switch, cross the bridge, and complete the glass
sculpture. Note: This must be done in Free Play mode.
Green Fingers: In the room where you first use your power to grow plants,
there is a ledge above the big plant thing. There are iron bars blocking the
left passage of this ledge. Blow it open, and use Robin in the Attract suit
to build a truck with a cake in the back. Bake the cake, and the Power Brick
will appear. Note: This must be done in Free Play mode.
