Timmy and Tommy Tibble

Timmy Tibble and Tommy Tibble are boisterous twin brothers in D.W.'s Preschool class. Together they are known as the Tibble twins or the Tibbles.

Description
Timmy and Tommy are bears in the show and humans in the book. They always dress identically. They normally wear yellow t-shirts, purple shorts, yellow socks, and black and white sneakers. As they are identical twins, Timmy always wears a blue scarf while Tommy wears a red one to differentiate. Originally in the books, they looked more like humans and less like bears, but that changed in the cartoon series. Notably, however, in even later book releases, they continued to appear as humans, despite the significant art shift in the books towards an appearance more in line with that of the television series.

Personality
Timmy and Tommy are mischievous, clever, reckless and often really mean and annoying (Sometimes one more than the other), though deep down they are good kids. Timmy is more independent and meaner than his brother, as seen in "Double Tibble Trouble" and "Attack of the Turbo Tibbles." In "Double Tibble Trouble" it is revealed that when Tommy is not with Timmy he becomes sad and behaves well, but at the end of the episode when Tommy gets sick, Timmy doesn't seem sad and behaves like always. In "Attack of the Turbo Tibbles," Timmy is the one who hurts D.W.. They each have their own ways of annoying others, usually by yelling louder than one another. Tommy also seems to have more of a sensitive side than Timmy.

Family
Timmy and Tommy live with their grandmother in a large house that looks almost haunted.
 * Mrs. Tibble: Timmy and Tommy's grandmother. She loves them very much but doesn't always show awareness of their bad behavior, though she does occasionally show signs of distress at their actions. In "Mind Your Manners", they force themselves to learn manners in order to take her out to dinner. They usually spend all of their time at her house when they're not in preschool.
 * Trixie Tibble: Timmy and Tommy's mother. She is first mentioned in "D.W.'s Backpack Mishap", where we find out that she used to take them on trips around the world.
 * Timmy and Tommy's Father: Although mentioned several times, not much is known about him.

Friends

 * D.W. Read: Timmy and Tommy are her friends but often try to compete with and pester her. They also sometimes trick her into doing foolish things.

Trivia

 * In "Bleep", Timmy can whistle, but in "Whistling in the Wind" he can't, however, it is possible that the events of the latter occurred before the former, or that Timmy might have learned to whistle during the course of these episodes.
 * In the episode "Two Minutes", it is been revealed that the Tibbles are at the same age.
