The Stuff screen is basically a menu where the player can select special treasures for Starfy or Starly to dress up in. In Densetsu no Starfy 2 and Densetsu no Starfy 3, the treasures are only split into two categories; Clothes and Extras (Accessories, アクセサリー in Japan). Clothes are basic items that Starfy and Starly can wear, while Extras are items that are wearable/holdable, but do not cover the body, such as the Baseball Cap (Japanese: やきゅうキャップ) from Densetsu no Starfy 2. Both Clothes and Extras can be worn together.
Clothes and Extras are unlockable by clearing stages, clearing minigames on 'Hard' mode (in Densetsu no Starfy 2 and Densetsu no Starfy 3) and purchasing them from the Shop.
Densetsu no Starfy 4 introduces another category to the Stuff, known as Specials (Japanese: スペシャル). Specials dress up Starfy or Starly completely (excluding a few items such as the Grandfather Clock) and may depict them in the middle of a scene. For example, the Beach Vacation Special from The Legendary Starfy depicts Starfy with the Beachwear lying on a bench chair. Specials cannot be worn in combination with Clothes and Extras or a wearable version of Bunston's powers.
In Densetsu no Starfy 4, Specials are unlocked through normal means like Clothes and Extras, excluding Nintendo Headquarters, which is a gift from Maniankou for purchasing every item from his Shop, excluding Konpeitou.
In The Legendary Starfy, Specials combine Clothes and Accessories to present a scene. They can only be unlocked by wearing an Extra with a matching set of Clothes.
The Legendary Starfy introduces the Bunston category (known in Japan as Rampa, ランパ). After the player unlocks one of Bunston's powers it becomes wearable as a costume in the Stuff (note: though Starfright is unlockable, it is unconfirmed whether Starfright appear in the Stuff upon unlocking it). Stuff from the Bunston category cannot be worn in combination with Clothes, Extras or Specials.
Some of the Stuff have gender differences between Starfy and Starly. In The Legendary Starfy, there are a few regional differences between the Japanese and North American/Australasian versions of the Stuff as well.

Some of the Stuff can be bought at Lovely's Shop. Some are unlocked by clearing levels, or clearing them again after beating the game once. Five are unlocked by completing Minigames on hard. There are 99 Stuff in this game. The game came with stickers of Starfy and some of the stuff.
Densetsu no Starfy 3
- Main article: Densetsu no Starfy 3/Stuff
Much like Densetsu no Starfy 2, Stuff can be unlocked by clearing levels, clearing them again after beating the game once, buying them at Jojiro's shop, and completing each of the five Minigames on hard. Sometimes characters give Starfy and Starly stuff as well. There are 99 costumes in this game.
Densetsu no Starfy 4
Stuff are normally unlocked by getting some from characters and buying some from Maniankou's shop. This is the first appearance of Specials.
Ten of the Stuff support the Nintendo DS microphone, with a few from each category. For these Stuff, blowing into the microphone will cause a special animation to play. Stuff that support the microphone have an animated sprite of Moe expelling air next to the 'tap the Touch Screen' icon on the top screen (), as well as a different top screen message which tells the player to try to blow into the microphone.
Before this game was released, there was a contest in Japan known as the Wanted Kisekae contest, where fans could mail over their design for a costume over to Nintendo's headquarters with a chance of their costume being featured in the final game. Six winning designs are in the game, and the entrants had their names featured in the Densetsu no Starfy 4 Staff Credits.
In Staff Roll 1, the original illustrations of costumes designed by various runner-ups are shown on the touch screen, although none of these made it into the final game.
Possible scrapped concept
In a text dump of the game, the text "Spill" (Japanese: スピル) appears directly after 'Special' (Japanese: スペシャル) in a series of names for types of Stuff but appears to be unused here. This may imply that wearable goods based on Spill abilities were once planned for the game, but only clothes, extras (accessories) and specials are wearable in the final game.
The Legendary Starfy
- Main article: The Legendary Starfy/Stuff
Stuff can be bought in Moe's Case and found in Treasure chests. Whenever the player gets a new Bunston transformation it becomes available in the Stuff. (Note: though Starfright is unlockable, it is unconfirmed whether Starfright appear in the Stuff upon unlocking it)
- Main article: Helpful Stuff.
There is unused text in the Japanese version of The Legendary Starfy referencing something that is supposedly the equivalent of Vehicles from previous games in The Legendary Starfy series called Helpful Stuff (Japanese: おたすけグッズ, Helpful Goods). Their name implies that they are a special kind of Stuff. They would apparently be used in boss battles in cooperative play. The Helpful Stuff would account for several elements including fire, ice and poison.
According to some unused text from Moe, there were supposedly eight different kinds of Helpful Stuff planned, however, following the names of Super Bugawk and Super Vanish in the ROM is the text "Helpful Stuff 9" and "Helpful Stuff 10". Although this may imply ten kinds of Helpful Stuff were planned, the names may have been added as placeholders because ten is a nice round figure.
- Densetsu no Starfy is the only game where the stuff feature was not available.
- Densetsu no Starfy 2 is the only game where only Starfy can be dressed up. This is do to the fact that Starly first appears in Densetsu no Starfy 3.
- Costumes of Mashtooth and Degil appear, but not Ogura and Evil.
- A lot of Densetsu no Starfy 3's stuff are someone else's things like Torito's hat and Kittana's eye patch.
- Densetsu no Starfy 4 is the only game that had a costume contest.
- The Legendary Starfy is the only game where transformations are featured in stuff.
