The Dinkleberg's live right next door to the Turner family. They have lived there ever since Mrs. Turner was pregnant with her son, Timmy. The Turners occasionally visit the Dinklebergs, usually to gloat about something, and Mr. Turner also directed a spying mission inside Dinkleberg's house.
Inside, the walls have a blue flowery wallpaper. There is a secret switch behind a picture of Dinkleberg with the president which turns his house into an evil looking intestinal lair with a lot of piranhas in a tank. Dinkleberg told Timmy he bought the lair as part of his way of keeping Mr. Turner happy by making him think he (Dinkleberg) is evil.
