Hi all! I am a huge Scribblenauts fan who played the original DS game religiously as a child in 2009. I still own the Prima Guidebook to this day!
I found there was a lot of interesting information regarding the development and behind the scenes of the game that to my knowledge I couldn't find elsewhere except the guidebook (Scribblenauts Game Guide p. 193-194, Catherine Browne). Particularly the behind the scenes interview with director Jeremiah Slaczka. I had no idea Shoggoth was an idea programmed late into development! I hope these sources provide valuable information to this wiki.
