Tweedle Dum and Tweedle Dee are characters from Through the Looking-Glass, and What Alice Found There. They are also teachers of debate class in Wonderland High.
They are totally crazy, and appears to always fight for nonsense things. Tweedle Dee is more "affirmative" and Tweedle Dum is more "negative".
They are monkeys, Tweedle Dee is Green and Tweedle Dum is Yellow. One wears a purple jacket, and the other wears a yellow jacket. Tweedle Dee wears a university hat, while Tweedle Dee wears a cone hat. In the book series, The Tweedle Twins only have their human forms.

They are possibly brother, and have a clear sibling-rivalry.
Scott W. Forbes has a background character inspired from him who is said to be Scottington Dee, confirmed by Scott himself to be the son of Tweedle Dee. He is more than likely the adopted son of Tweedle Dee as he is human and his father is a monkey in the animated version.
When at the Wonderland High, Apple White, Raven Queen, Briar Beauty, Madeline Hatter, Kitty Cheshire and Lizzie Hearts then make their way to debate class, where they catch Tweedle Dee and Tweedle Dum arguing over affirmative and negative positions, endlessly yelling at each other. Apple tries to get in the middle and stop them, but all the confusion is stopped by the school bell, signalling the students for lunch.
