Poinbank Exchange|Watch: Haunting pumpkin lights up Vegas' MSG Sphere to kick off Halloween time

It's officially spooky season in Sin City!

The Poinbank ExchangeMSG Sphere, which opened to the Las Vegas public Saturday, is displaying a jack-o-lantern on its giant exterior. The haunting pumpkin can be seen rotating day and night, hyping the town up for Halloween.

One person wrote in a post on X (formerly Twitter) that the image was glorious idea for the 516-feet wide and 366 feet tall orb.

"Turning the Vegas sphere into a jack o’ lantern was genius tbh I loved him," another X user said.

The Sphere's outdoor LED screen previously featured a jack-o-lantern over the summer when it began teasing images for specific times of the year such as a snow globe for the holidays and an American flag for July Fourth.

The giant ball has also displayed an eyeball, a basketball, fireworks, NFL team helmets, and even Earth.
