-After you complete "Projector Heist", go by the tree stump in the woods. The two possums will be watching Shrek Super Slam on the film projector.
-The projector and laptop show various DreamWorks video game screens. The laptop always shows Shrek Super Slam. The projector is different, however. From when you first get the projector until about half way through, Shrek Super Slam is on the screen. From about halfway through the game until just before you play the final level, it plays Shark Tale. After you play the last level it will show Madagascar. However, even though they show the video games the animals sitting next to the projector will talk as if they were watching the actual movie.
