Electroplankton - it's kind of a rhythm game, but not really. You can make your own music. No plot or anything, just mess around and make noises. No skill required.
Kirby Canvas Curve - great game that really uses the touch screen to its full potential. Highly recommend.
Kirby Super Star Ultra
Mario Kart DS - You don't have this? It's one of the best MK games!
Okamiden - Kind of Zelda-esque in that it is an adventure/puzzle game
Super Scribblenauts For the love of all things good get this!! It's amazing! Or get Scribblenauts Unlimited, a 3DS/Wii U/PC title
If you were only to get one game from this list, make it Kirby Canvas Curse. You gotta add this game to your collection.
Been away for a bit, but sneaking back in.
Gaming on: PS4, PC, 3DS. Got a Switch! Mainly to play Smash
