Kirby sucks on the DS, and that's a good thing!
Kirby DS is a very traditional Kirby game. There are a few levels playable on the show floor at E3 2006. The major change to the game is that you can now access Kirby’s stomach. Kirby can hold five items in his stomach, including powers. However, the only powers that Kirby can hold are ones he finds in bubbles. Food and treasures can also be held in reserve. Items can be combined to form more powerful items. For example, two pieces of food can be combined to make a Maxim Tomato. Powers can also be combined. However, from what we could tell, two powers do not combine to form a specific special power, as they did in Kirby 64: The Crystal Shards. Instead, mixing two powers gives you a random power. Treasures that are held in Kirby’s stomach will be unlocked at the end of the level, and contain unlockable bonuses such as songs. Other than this change, Kirby DS plays very similarly to the Kirby Games on Game Boy Advance.
