Nintendo seems to be starting at the brain and slowly working outwards when it comes to training. Their latest Japanese training title translates roughly to Face Training, which has you training with the use of a new Nintendo DS camera. We don't know if the game recognizes when you are doing the proper facial expression and moves on from there or if you're just supposed to look at yourself in the screen to make sure you're doing it right.
The game is hosted by Fumiko Inudo who is apparently a face expert like the disembodied head of Dr. Kawashima is a brain expert. The game was apparently co-developed by the creators of Fire Emblem and releases in Japan on August 2 with no US announcement made (yet?). We're still holding out for Dream Skincare to help us cover up years of Cheetos abuse.
