Tommy Tibble and Timmy Tibble are energetic twin brothers in D.W.'s class, and D.W.'s frenemies. Together they are known as the Tibble twins[5] or the Tibbles. They tend to be the main antagonists of D.W.'s own episodes.

Physical appearances

Timmy and Tommy are bears in the show and "Step Into Reading" books, and humans in the other Arthur-related books. 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 themselves. Even when wearing different clothing, they always wear something blue and red. It is implied that even Ms. Morgan cannot tell them apart when they switch scarves.

Originally in the books, they looked more like humans and less like bears, but that changed in the TV 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 TV series.

In a flashback scene in "Tales from the Crib," they had a more slimmer appearance in comparison to the other younger kids such as D.W. as toddlers. It is implied that they got slightly chubbier while living with their grandmother.

In "Dancing Fools," they both wear navy blue sweatpants with a yellow stripe and dark-grey sneakers. Timmy wears a blue shirt, while Tommy wears a red one, each with yellow design.


Without stopping to take a breath, Timmy Tibble can yell for five minutes. And Tommy Tibble, sometimes it seems like he's four kids!

Arthur Read, "Attack of the Turbo Tibbles"

Timmy and Tommy are mean, energetic, rambunctious, mischievous, clever and reckless (sometimes one more than the other), though deep down, they are good kids. Timmy is more independent than his brother, as seen in "Double Tibble Trouble", and "To Tibble the Truth". "Two Minutes" and "Whistling in the Wind" reveal that Tommy is two minutes older, causing him to act superior to Timmy in both episodes. In "Double Tibble Trouble," Tommy is less energetic and feels sad when Timmy is sick, but at the end of the episode, when Tommy gets sick, Timmy doesn't seem sad and behaves like he always does.

Their personalities can be described as manipulative (for instance, when they trick people so they can get what they want as is seen in several episodes, dishonest, and sadistic. They could even be described as fair-weather friends (which refers to someone who only helps when it's advantageous to themselves), as is the case in "Never, Never, Never" where they trick D.W. into thinking they care about her in order to get her toys and destroy them in front of her face. Normally, their personalities are identical except for a few episodes, e.g. "My Fair Tommy" where Tommy is slightly nicer, and Timmy is more manipulative.







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. The Tibbles do not tell her about their misbehavior, and when they do, they censor it to not sound like bullying. [6] 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:[7] Timmy and Tommy's mother. She is first mentioned in "D.W.'s Backpack Mishap," where it's revealed that she used to take them on trips around the world.

  • Tommy and Timmy take folk music lessons, with Tommy playing the panpipes. [8]
  • There have been a few episodes where Tommy appears without Timmy, but Timmy has never once appeared without Tommy.
