A visitor to the Infinity Mirrors art exhibition in Washington lost their footing whilst reportedly taking a selfie and damaged a sculpture.
The guest fell into one of Yayoi Kusama's signature polka-dot pumpkins, in the All the Eternal Love I Have for the Pumpkins room of the exhibition, Newsbeat said.
The exhibition had to be closed due to the incident for three days, while the pumpkin was removed and the art was repositioned to account for it, The New York Times said.
However the museum has said a replacement pumpkin will be put in place.
The room where the incident happened is one of six immersive rooms which have been created to celebrate the artist's 65-year career.
It holds more than 60 pumpkin sculptures, which glow from within by using LEDs across the floor.
A similar sculpture sold for £635,000 in 2015, according to Artnet, however a spokeswoman for the Hirshhorn Museum, Alison Peck, told the New York Times that as the pumpkin was part of a larger piece, and may not necessarily be worth as much.
