They are two identical twins of the McNulty boys. Teddy & Terry are Timmy's slightly-younger brothers, both boys are in potty training and very loyal to their family and follow Timmy's orders such as the babies follow Angelica's. The twins are used in Angelica and Timmy's "olympics" as they compete in a mudd dancing contest with Phil and Lil. They lose to Phil and Lil's tango. Teddy and Terry mirror Phil and Lil of the McNulty group.
