|Owned by:||The Ghost of Shadow|
Coolsville is a town where all the Scooby Doo characters live. Its only appearance was in Wario and Waluigi's Super Adventures Ep. 1-5. The ghost of Shadow came up with its name, and all of its inhabitants are scared of him.
Coolsville's only appearance was in this video. The Wario Bros. were teleported here, and met the Scooby Doo gang, who cowered in fear of the Ghost of Shadow. Later, Shadow arrived, saying "It's time for your Scooby Dooby Doom!" However, he wasn't content with the setting, and said "This setting is LAME. Let's go somewhere COOLAH!" He then yelled "Shazam!" and they were all teleported to Bikini Bottom.
- Shadow's appearance as a ghost in this area is likely a reference to the Scooby Doo franchise, where Mystery Inc. investigates ghost problems.
