Club Pingas is a nightclub that is owned by Dr. Robotnik. It appears for the first time in Retarded64: Son of a Bowser, and then again in SMG4 Bloopers: Shell Shocked. Not much is known about it, other than the fact that Dr. Robotnik owns it and that it has a Teletubbie stripper.
In Son of a Bowser, Dr. Robotnik is seen as the owner of the club. Mario and Bowser go to this club in attempt to find Bowser Jr. after Bowser accidentally called him a bad name. Bowser Jr. is found in this club with his "new cool uncle." As they find him, Mario passes out, while Bowser accidentally breaks a hole in the building, angering Dr. Robotnik.
In Shell Shocked, it is where Mario and company are celebrating Toadsworth's "birthday" before an un-dead Koopa Trooper comes in searching for shells. After a brief encounter between Toad and the Koopa Trooper, the club finds itself in disrepair, much to the horror of Dr. Robotnik.
