Secret 1966 Batman Show Bonus Level:
Successfully complete the game to unlock the "Same Bat-Time! Same Bat-Channel!" bonus 
level. Go to the Batcave's main room, and fly up to the elevator with the Bat-logo to 
the left of the Batcomputer. When in the trophy room, fly to the far right to reach the
studio set, which looks similar to the Wayne Manor study in the 1966 Batman TV show. 
Switch to Batman or any character with a grapple gun. Pull the grapple point to the 
left of the bookcase to reveal a secret passage. Slide down the pole to start the bonus

Hidden doughnut locations:
Search the indicted location on the listed hub planet to find a hidden doughnut. Destroy
a hidden doughnut to get the "Doughnut Discoverer" achievement.

During Loontern's second quest on Nok, you will need to defeat 20 enemies in a prison area.
Search the top level of cells to find the hidden doughnut.

Look for a burning building on Ysmault, where the Heatwave character stud is found. There
is a crack in that same building that can be smashed open with a super strong character 
to reveal a doughnut.

Teleport to Zamaron, and use a flying character. Fly over the teleporter, and go past 
the Star Sapphire minifig statue. Just north and a little west of the statue is a rocky
hill with crystals sticking out. The rocky hill is close to the starting point for 
Loontern's third quest. There is a tiny donut on the top of the hill. Land and walk into
it, or hit it, to collect the doughnut.
