Gadd]] and is usually emblazoned with his logo, although he and the brush have never physically appeared in the same game. The magic brush can create [[graffiti]] that has many functions, from generating [[Proto Piranha]]s to acting as [[Rainbow M|portals between locations]] to creating items. [[Mushroom Kingdom pop quiz|A skill quiz]] on the [[Play Nintendo]] website conjectures that Bowser Jr. drew the toothy grin on his bib by using the magic brush.<ref name="Play Nintendo"/>

After obtaining the magic brush from E. Gadd, Bowser Jr. uses it to paint graffiti all over [[Isle Delfino]], fill it up with hostile creatures,<ref>An excerpt of page 107 of the ''Encyclopedia Super Mario Bros.'' The title of the box is 「クッパＪｒ．の落書き!」 which means "''The graffiti of Bowser Jr.!''" and the text says 「本作の敵キャラクターたちは、クッパJr.が落書きで生み出したという設定。そのため、水に弱かったり、デザインが他のシリーズと少々異なっていたりする。ヨッシーも、同様の理由で水に落ちると消えてしまう。」 which means "''This game's enemy characters are created by Bowser Jr.'s graffiti. That is why they are weak to water, and differ slightly in design from the rest of the series. Yoshi also vanishes if he falls in water for the same reason.''"</ref> and disguise himself as [[Shadow Mario]]. Because of his disguise, [[Mario]] is believed to be the perpetrator and is forced to clean up the [[goop]]. Bowser Jr. claims the magic brush was given to him by E. Gadd as opposed to stealing it. Most of the game's enemies, puzzles, and hazards revolve around the goop and graffiti created by the brush, which can take on caustic and elemental properties to damage Mario on contact. The brush's goop is washed up using [[F.L.U.D.D.|FLUDD]], and by the time [[Bowser]] and Bowser Jr. are confronted for the final time, Mario has washed up nearly all of it.  

The magic brush makes an appearance in the ''Bowser Jr.'s Journey'' sub-mode of ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]''. Bowser Jr. wields it when changed to ranged-type and uses it to sling paint at enemies. [[Morton|Morton Koopa Jr.]] had it under his possession for a while without Bowser Jr. knowing, causing the latter to scold him upon discovering this.
