An observatory at Carleton College was decorated to look like familiar Star Wars droid R2-D2 as a prank by a group of students.

The pranksters draped several white bedsheets with blue and black spraypaint around the building and stuck sheets of paper on the dome and entrance to mimic the droid’s likeness. They even have the sound effects going on in the background while [I’m assuming] employees assess the situation and enter the facility.

For photos of the R2-D2-ized observatory, check out the college’s Facebook page or watch a video of the prank below, which is awkwardly filmed sideways, but no less impressive.
