Magic Paintbrush

"This...is my magic brush. When I draw with this, all my wishes come true! A strange old man in a white coat gave it to me..."

- Bowser Jr.

The Magic Paintbrush, also known as the Gaddbrush in the Prima strategy guide for Super Mario Sunshine, is a strange weapon wielded by Bowser Jr. in Super Mario Sunshine. The young Koopa used the brush to paint Goop and graffiti of various shapes including "△"s, "O"s, "X"s, and "M"s all over Isle Delfino under the guise of Shadow Mario. He pinned the blame on Mario, who was sentenced to cleaning up the entire island as community service.

History
Apparently, the brush was created by Professor E. Gadd, as Bowser Jr. claimed that he got the brush from a "strange old man in a white coat." Additionally, the brush has the E. Gadd logo on it, as does F.L.U.D.D., who reacts with surprise when Bowser Jr. informs Mario of this. It is unknown exactly how Bowser Jr. got the weapon. One theory suggests that E. Gadd gave Bowser Jr. the brush, or Bowser Jr. simply stole the brush from E. Gadd. Once Bowser Jr. obtained the Brush, he began to cover Isle Delfino with toxic Graffiti.

After the final battle on Corona Mountain, Bowser Jr. dropped his paintbrush. It was later discovered by Il Piantissimo near Gelato Beach.

Other Appearances
Bowser Jr. somehow recovered the weapon prior to the events of Mario Power Tennis, where he used the brush to perform special moves. Several Magic Paintbrushes later appeared on display in Mario Kart Arcade GP ' s Diamond City course, and Bowser Jr. used it again in Mario Hoops 3-on-3 in his Special Shot, Graffiti Shot. The Paintbrush gets a "look makeover" when it appears in Mario Super Sluggers, as one of the items used in Bowser Jr.'s Special Shot. Bowser Jr. even has it as a bat in Mario Super Sluggers, replacing his little spiky bat from the prequel. Also in Mario Super Sluggers, there is a mini-game called "Graffiti Runner" where the player finds the Brush and uses it to paint the floor the player's color to win. If the player uses all the paint, the player loses it, so the player has to grab it again to continue. The Magic Paintbrush also appears for Jr's Special Shots in Mario Sports Mix.

Trivia

 * The tip of the brush almost looks like F.L.U.D.D.'s head, except for the presence of the bristles on the brush, of course.
 * In Mario Super Sluggers, the majority of this part of the brush is absent, and all that remains is the silver part which contains the brush bristles, which still slightly resembles F.L.U.D.D.'s nozzle.
 * When Bowser Jr. masquerades as Shadow Mario, the Magic Paintbrush changes color to match his shadowy consistency. It is only when he becomes Bowser Jr. again that the true coloration of the Magic Paintbrush is revealed.
 * In the Prima Game Guide for Super Mario Sunshine, it was said that E. Gadd gave the Magic Paintbrush to Shadow Mario thinking that it was Mario.
 * The Magic Brush can be seen as Bowser Jr's equivalent to the Koopalings' Magic Scepters in Super Mario Bros. 3, as they are both magical devices are used by the princes of King Bowser to accomplish the goals that are the major sources of antagonization for Mario to deal with. It should also be noted that both the Magic Brush and the Magic Wands were used by Bowser Jr. and the Koopalings, respectively, in their debut game, having both been taken by allied characters of Mario.
 * In Mario Hoops 3-on-3, Bowser Jr. is once again able to use his Magic Paintbrush for his special Graffiti Shot.
