Tweedle Dee and Tweedle Dum are characters from Disney's 1951 feature film Alice in Wonderland, originally featured in the original book's sequel, Alice Through the Looking Glass. Despite their short amount of screen time, they became memorable Disney characters. They were originally voiced by J. Pat O'Malley and now voiced by Corey Burton.
The Tweedles are two fat brothers dressed in school boy uniforms and wearing propeller caps. They take particular delight in reciting poems and songs. They're playful and jolly which can seem a little annoying. They enjoy company and will always insist in a little game. They also have the ability to multiply.
In the movie when Alice tries to chase after the White Rabbit she comes across Tweedle Dee and Tweedle Dum. The twin brothers offer to play a game called Who's Got the Button? or fight each other to which Alice turns down as she explains that she's following the White Rabbit because she's curious to know where he's going. This makes the brothers think about the Little Oysters who were curious and that something sad happened to them when they were. Alice decides to stay to listen to the story which is actually a poem called The Walrus and the Carpenter. Tweedle Dee and Tweedle Dum tell Alice how one time in the middle of the night The Walrus and the Carpenter managed to lure the Little Oysters away from their mother in the sea and offered them to dinner. Then while the Carpenter went to get some stuff to go with the meal The Walrus ate up all the Oysters for himself making the Carpenter mad and the Carpenter chased the Walrus away. At the end Alice tells Tweedle Dee and Tweedle Dum that the story was very sad to which the brothers reply Yes. And There's a moral to it. To which Alice replies "Oh yes a very good moral. If you happen to be an oyster". She then tries to leave but Tweedle Dee and Tweedle Dum insist that she listen to another one called Father Williams but when the brothers aren't looking Alice manages to sneak off and continue her search for the White Rabbit. Tweedle Dee and Tweedle Dum are seen again briefly during the scene when Alice is running away from the Queen of Hearts before she wakes up from her dream.
The Tweedles make a brief appearance during chapter 1 of the comic book based on the movie. The Queen intended to execute them both at the same time for the crime of "being unneccesarily annoying" (which is a fitting accusation, given their characters). However, they are able to escape their punishment by lying that the White Rabbit was conspiriting against her with the "Alice Monster". The duo are last seen munching on the Queen's various pastries while the Queen angrily rushes off to kill the White Rabbit.
One of the Tweedle Brothers (most notably Tweedle Dum) can be spotted during the final scene of Disney's (Touchstone's) 1988 hit Who Framed Roger Rabbit. He is seen in a brief back view leaving toward Toontown while the song is finishing.
Tweedle Dee and Tweedle Dum along with Alice, The March Hare, The Mad Hatter, and the Cheshire Cat make appearances as guests at the House of Mouse.
When Alice returns to Wonderland with Will and the White Rabbit, they immediately find themselves in a sticky situation; quite literally. The two amateur portal jumpers land in a mallowmarsh and begin sinking. A worried White Rabbit runs off to get help for them. He runs down a seemingly quiet road in Wonderland, but he soon stops when he comes across something terrifying to him; the Red Queen's royal carriage. Tweedledum and Tweedledee, who are both dressed in masquerade styled clothes and are both presumably working for the Red Queen as slaves under a threat, open the door and accompany her majesty off the carriage so she can meet with the rabbit. Another guard apprehends the rabbit and the Red Queen approaches him, with Tweedledum and Tweedledee by her side. She angrily tells the rabbit that he's late, to which he responds that he came as fast as he could. The party then take him back to the queen's palace, where it is revealed that the White Rabbit is working for the queen under threat of death, and he brought Alice back to Wonderland per her request.
The Tweedles are rarely-seen meetable characters at all theme parks except Hong Kong Disneyland, and have appeared in parades there.
The tweedles make occasional appearance in the fun game hosted by Mad Hatter and Alice at the Disneyland park.
