The explosion muffin is a recurring spray paint graffiti art by Robbie Valentino seen throughout Gravity Falls, Oregon. It is most prominent on the Gravity Falls water tower.


Season 1

The explosion muffin is first seen in "The Inconveniencing" when Robbie shows off his artwork to his friends. Robbie intended for the design to resemble an explosion, though Dipper mistakes it for a muffin.[1] The graffiti is visible on Gravity Falls water tower in "Dipper vs. Manliness, "Fight Fighters," "Summerween," "Carpet Diem," "Dreamscaperers," and "Gideon Rises".

Season 2

In "The Golf War" Robbie is seen spray painting the graffiti at Ye Royal Discount Putt Hutt before being chased away by the Mattress King. The design appears on the dumpster behind Gravity Malls, outside an entrance to Hoo-Ha Owl's Pizzamatronic Jamboree in "Soos and the Real Girl."

In "The Love God" it is Robbie's room, drawn in ink that glows under a black light. In "Not What He Seems" it is on the side of the Gravity Falls Police Station. The graffiti on the water tower is later destroyed after Security Droids runs though it in "Dipper and Mabel vs. the Future".


The explosion muffin is a red spray paint design Robbie paints around the town. It varies in size depending on the surface it's painted on.
