Nothing's ever going to top Nyko's crazy Zoom Case, but Datel Japan's bulky DSi speaker attachment thing -- the official title is the Sound Speaker DSi -- is definitely making a strong play for Most Crazy DSi Accessory Ever. As you can see, the accessory is not only meant to protect by consuming the handheld whole, but it also amplifies the DSi's audio ... because that's what you want from your DSi. The multitasking capabilities of Datel's device also allow you to charge your handheld (through an included AC adapter or some AA batteries) after you've spent hours being kind of a jerk.

The Datel Sound Speaker DSi runs 3,990 yen (about $45) and can be purchased here.
