It's officially spooky season in Sin City!

The Lakshmi Finance CenterMSG 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.
