The Hall of Timmy is a big hallway completely devoted to Timmy. A plethora of Timmy's pictures cover the golden walls of the room, showing just how much Cosmo and Wanda really love and care for Timmy. Each picture is hung up in a shiny golden picture frame, ranging from a round frame to a square frame. In the middle is a red poster which indicates that this is the hall of Timmy.
In Hassle in the Castle after Timmy got mad that his picture wasn't on the Hall of Fame, he found out that Cosmo and Wanda had been building a room in his honor called "Hall of Timmy."
