Trombone Gobble
When the alien shakes its head after Scooby-Doo squirts a stream of milk on its face, the classic "Trombone Gobble" sound effect from many old Looney Tunes and Merrie Melodies cartoons produced by Warner Bros. Animation can be heard. Other classic Looney Tunes sound effects often show up in the series (often in place of the Hanna-Barbera sound effects, which the older Scooby-Doo shows used instead!) Edit
