The Bimbettes

The Bimbettes are a trio of exceedingly ditzy, beautiful blonde women who fawn over Gaston in Beauty and the Beast. They wear red, yellow, and green dresses.

Background
The Bimbettes (real names Claudia [Red dress], Laura [yellow dress] and Paula [green dress]) are triplets and waitresses of a tavern, they really love Gaston, who has no interest in marrying any of them, because he wants the best girl only for him, and since they are triplets, two other men in the town will have an exact girl in appearance. Claudia has Jasmine's hairstyle, Laura has Vanessa's/Belle's, and Paula has Ariel's. However, at the end of the reprise to Gaston, all three girls have Jasmine's hairstyle, likely as the result of an animation error that could not be fixed in time for the movie's release.

Beauty and the Beast
They first appear in the introduction song of the film, where they are remarking on how Gaston's dreamy and a strong brute. Afterwards, they, while witnessing Belle rejecting Gaston's advances, state how Belle is crazy because of the way she deals with Gaston. They are also devastated when Gaston decides to marry Belle, as they are seen crying streams of tears and blowing snot rockets when he is announcing that he will propose to Belle, although they later comforted him at the Tavern after his plan to marry her backfired with him falling into mud. They were apparently also in support of Gaston's plan to blackmail Belle, but despite this were not present at the Lynch Mob that congregated at Belle's house to evict Maurice to the Asylum. The Bimbettes aren't seen throughout the rest of the film after this, nor do we see their reaction to Gaston's death.

Beauty and the Beast (musical)
In the Musical, their roles are the same, although they are given more dialogue, Gaston pays more attention to them, and their role is expanded slightly. It is also implied that Gaston might still see them after he marries Belle when they are upset that he's marrying Belle. They are referred to as the Silly Girls in the musical, and there can be more than three of them if a director chooses to. However, in the original Broadway musical, similar to in the original film, they do not appear during The Mob Song, but can appear if a director chooses to expand their role further. Additionally, some school productions of the musical have Bimbettes of different races.

House of Mouse
The Bimbettes appear several times in the show as cameo characters. In the episode "Big Bad Wolf Daddy", Gaston sees to be annoyed with them singing a song with Zeke Wolf, even if he ignored them in the movie. They also acted as groupies for Donald Duck in the episode "Three Caballeros", when the duck became The Duck Formerly Known as Donald--they called Donald "super-duper duck-a-riffic".

Trivia

 * The ones in the red and yellow dresses were voiced by Mary Kay Bergman and the one in the green dress was voiced by Kath Soucie (Who coincidentally voices The Enchantress in The Enchanted Christmas, who bears some resemblance to her).
 * In House of Mouse, they are all voiced by Kath Soucie due to Mary Kay Bergman's death by that point.
 * In Phineas and Ferb, the Ferbettes parodied the name.
