Adventure Time 'collector's edition' spotted

A Collector's Edition of Adventure Time: Hey Ice King! Why'd You Steal Our Garbage?! has popped up over at GameStop, presumably as a retailer exclusive – we're checking on that. Both the 3DS and DS version toss in a custom stylus shaped like Finn's sword, Land of Ooo poster, steelbook packaging made to look like the Enchiridion (the handbook Finn is always lugging around) and an art book.

It's a pretty significant package for $39.99. We've also inquired about a regular version, one that could possibly be cheaper and void of less awesome stuff.
