− Maxwell, a young child, had been helping many people with his problems since he found the magic notepad, when one day, the vile Doppleganger appeared and had a notepad of his own. "Foolish Maxwell" the Doppleganger sneered, "Didn't you know I am a Scribblenaut as well?" Doppleganger wrote a word in his notepad, and a huge, blue Cthulu with a black star on his chest appeared. Maxwell ran off, but not before the blue Cthulu could whack Maxwell across the country. When Maxwell awoke, he was with a female Scribblenaut named Annabell was right there. Maxwell tilted his head as if to say 'Who are you?' and Annabell responded with a shrug, as if she did not know who she was either, except her name. Annabell held up her notepad and showed a word written in it. 'Dracon' it said. Maxwell tilted it's head again. In response, a large, red, friendly dragon named Dracon stepped out of the bushes. The three learned that Doppleganger had stolen some of the most powerful words in the universe, and these words were all extremely strong monsters, such as the Cthulu, which Maxwell had seen earlier. Now the three must go stop Doppleganger!
− As Maxwell or Annabell, you can play a level. Annabell plays just like Maxwell but she can jump higher, but not run as fast. You can only write some words in the notepad, and Dracon you can only write if you have enough energy. You also cannot write the words for the boss battles, which are featured at the end of each world, and the bosses always steal your notepad so that you can only use what's around you to defeat the boss. After defeating the boss, you can write them whenever you want.
