|“||Most of Ripple Field is under water. Be sure to look for Kine and watch out for Sweet Stuff!”|

In addition to appearing as a boss in numerous games, Sweet Stuff also had a cameo in the Kirby of the Stars Pilot before making his latest appearance on Adeleine's collectible Keychain in Kirby: Triple Deluxe.
Sweet Stuff debuts as the boss of Ripple Field, the third world in Kirby's Dream Land 2.
The battle takes place in a deep sea trench, with the screen scrolling horizontally. It swims around accompanied by Squishies and small one-eyed starfish called Tincells. These foes can be blown back at it to deal damage. Sweet Stuff can also fire sparks and arrow-shaped lasers from Its lure.
This battle is similar to the second phase of the Acro battle in Kirby's Dream Land 3.
Adeleine paints a copy of Sweet Stuff to engage Kirby in battle during the Cloudy Park boss battle.
Because this fight takes place in a cloudy arena devoid of water, Sweet Stuff bounces around instead of swimming. Sweet Stuff can still fire sparks and Tincells. After Kirby depletes the painting's health, it explodes and Ado paints Mr. Shine & Mr. Bright to take its place.
It has a total of 500 HP and gives 1400 exp when beaten. If Kirby misses during any of his turns, Sweet Stuff will counterattack by shooting bolts of electricity. If the other foes are still there, they will join the counterattack and rush at Kirby. This is a direct callback to its attack pattern in Kirby's Dream Land 2.
Sweet Stuff's Japanese name is likely derived from the Japanese word for "angler" or "sea devil," 鮟鱇 (ankō). Anko (餡子) is also red bean paste, an East Asian cuisine. Anko is a sweet food, and thus could be further changed from "sweet food" to "sweet stuff."
- Kirby Mass Attack is the only game in which Sweet Stuff appears with the color palette from its official artwork. While Sweet Stuff does appear brown and yellow in Kirby's Dream Land 3, this is a painted replica created by Adeleine, not the real boss.
