I wonder if maybe I'm too dumb or unimaginative to play Scribblenauts games.  In Super Scribblenauts, you can now add adjectives to every noun in the world, and they actually react appropriately.  The demo was in Playground mode, so it entirely depended on me to think of things, and I didn't do a good job.
 
Purple Vampire.  Yes, it was purple.
Cowardly Vampire Hunter.  He was eaten by the Vampire and became a Vampire also.  Then I took the stake he dropped and killed them both.
Angry Fridge.  Man that Fridge is really aggressive and volatile.
Hungry Caveman.  I accidentally put him in the Fridge and his status changed to Cold.  Then he beat up the Fridge.
Happy Dragon.  I flew him around and set fire to the Caveman. 
Explosive Hot Air Balloon.  It exploded.
Lazy Griffin.  It moves incredibly slowly, but still attacked me and had to be destroyed by my Dragon.  Also you can pet the Dragon.
 
At this point, the presenter was trying to suggest fun things I could write, but I decided to move along and give someone else a turn.  Listen: It works.  Also, you can move your guy with the D-Pad now, and that is 1,000 times better than with the stylus.  This is probably a great game if you are smarter than me.
