If you pre-order the Scribblenauts Unlimited Special Edition (Nintendo 3DS) from EB Games for $58, you will get a Maxwell Silicon Case and a Pencil Stylus. Sounds like an alright deal, considering that JB Hi-Fi is charging $59 for the standard version.
P.S. It looks like the case will only fit the standard Nintendo 3DS, so if you are like me and have the 3DS XL, you are out of luck.
Oh man… not sure if want or need…
