Dark Helmet has coffee while watching Radar, as always
Mr. Radar was a device on Spaceball I that was capable of tracking nearby spaceships and planets. It was located right next to Mr. Coffee.
After being notified that Planet Druidia was in range of the Spaceball I, Dark Helmet needed to use the radar to view Druidia as it was not yet capable to be seen visually from the ship. Despite Colonel Sandurz offering to punch it up for him, Helmet stubbornly went over to check the radar himself, only to be confused by its churning and bubbling graphics. Helmet soon realized he wasn't actually looking at the radar, and instead Mr. Coffee. After getting a cup, Helmet was shown Mr. Radar where he was able to view Planet Druidia, and discuss the Spaceballs' evil plan to kidnap Princess Vespa and steal all their air.[1]
