Attributed only to "some hackerish type" who took apart the ROM, Scribblenauts' full dictionary has - inevitably - made it to the Internet. In terms of scope, this is the biggest spoiler alert we can offer.
For those who want to discover everything that's in this amazing game for the DS, on their own, avert thine eyes. For others who aren't buying it, or don't mind otherwise, this list provides hours of reading fun. I'd suggest printing it out and keeping it in the bathroom, it's a great timekiller for taking a dump.
Here are a few I found intriguing.
Air Raid Shelter
Claret Jug (as in the trophy from The British Open?)
Druid
Microraptor
Steak Fries
Velvet Rope
The Reddit thread that discovered this also has some amazing combinations from their commenters.
