Monster High: Why Do Ghouls Fall in Love? is the third Monster High special that was released on December 21, 2011.
Draculaura’s Sweet 1600th birthday is an extra special occasion to party at Monster High! But her high expectations lead to deadly results when she’s faced with the choice between practical boyfriend Clawd, and new vampire heartthrob, Valentine, a romantic blast from her past. Her ghoulfriends find it odd that Valentine created a holiday in her honor, but oddly named it after himself (how romantic?) and have to stop him before he steals her heart… literally. Draculaura must decide which boy is right for her before the party! Will she find out about Valentine’s sinister plan? Will her best ghoulfriends be able to help her in time? And most importantly… will Draculaura pass her driving test?
Draculaura is daydreaming about her ideal Sweet 1600 party in the catacombs, which Cleo and Clawdeen agree to make happen. Frankie then explains that Draculauras birthday was in a few days, and Clawd attempts to get Draculaura a gift, but ends up getting scolded by Clawdeen, which eventually leads to him asking C.A. Cupid for help, but it doesnt turn out well when he builds her a stepstool to reach things in her locker, which makes Draculaura think that Clawd thinks shes short. Draculaura soon reveals she used to date a boy named Valentine, but she had to move away from him.
Toralei and her crew hears this, and she hatches a plan to get back at the ghouls for not inviting her to Draculauras Sweet 1600th. Meanwhile, Ghoulia cant decide whether to take Slo Mo or Don of the Dead to Draculauras party, and tries to find out who she should take with Gil and Lagoonas help, but she decides to do it scientifically. Clawdeen and Cleo try to find an old concert hall in the Catacombs, but nearly fall into the pit of Eternal Body Odor, but they are both saved by Operetta. They then ask her if they can set up Draculauras party in the Catacombs, and Operetta approves. Toralei begins her plan by calling Valentine (while imitating Draculauras voice), which causes him to transfer to Monster High.
Ghoulia then finds Heath Burns is her perfect match, and Clawd decides to give Draculaura a box of the items that reminded her how she fell in love with him, but she finds out that Valentine transferred to Monster High, and starts spending time with him. Draculauras friends confront her about it, and they admit that while Clawd obviously isnt perfect, he genuinely cares about Draculaura, and is going to find out eventually about the time shes spent with Valentine. Clawdeen tells Draculaura that she cant have it both ways; she has to make a choice: either Clawd or Valentine. Draculaura soon realizes that while she has enjoyed spending time with Valentine, she really has moved on from him to Clawd, but after she confesses this to Valentine (who has been revealed to purposely break the hearts of the girls he originally dated, once they were totally in love with him, he would harvest their hearts). Hes forced to hypnotize Draculaura into loving him. The ghouls soon find out by sending Spectra to spy on Valentine, and find out that Toralei put him up to it, and on Draculauras birthday, shell be permanently under his control. The ghouls then turn to C.A. Cupid, who agrees to help them by shooting Draculaura with one of her arrows so she will fall in love with Clawd.
However, Toralei foils her and she and Clawd end up falling in love with each other. Frankie and Abbey then go back up to Cupids tower, where they try to find a way to break the spell so Clawd can show Draculaura the box. They are successful when they learn they can break the spell by smashing the bow, and they decide to do it at Draculauras party, where everyone will be. Cleo and Clawdeen then make copies of the key to the concert hall and give them to Cupid, Clawd, Valentine, Draculaura, and Jackson because he will need to turn into Holt Hyde to be the DJ. On the night of the party, Frankie is about to smash the bow, but its quickly stolen by Toralei, who begins to shoot random monsters, including Cleo and Gil. Clawdeen then hatches a plan to use herself as bait to distract Toralei while the others get the bow.
Clawdeen is shot and falls in love with a nerdy monster, but Frankie removes her hand, which knocks the bow out of Toraleis grasp, Lagoona spills water on the floor, and Abbey freezes it which causes Toralei and her crew to slip and Toralei ends up dangling from the banner. The ghouls smash the bow, which frees everyone from the spell, Clawd then tries to show Draculaura the box but is pinned against the wall by Valentines magic. However, Clawd still manages to convince Draculaura to look in the box which reminds her why she fell in love with Clawd and breaks free from Valentines spell, she then confronts Valentine who is driven toward the edge of the pit of Eternal Body Odor, Toralei then falls on him and they fall into it together.
Draculaura and Clawd then share a kiss, Abbey helps C.A. Cupid with her radio show, Ghoulia, realizing that her computer was literally bugged, tries to tell Heath shes not compatible with him, is interrupted when he tells her that after Valentine fell into the pit, all the girls who were crazy about him moved on, so he breaks up with her. The movie ends with Clawd and Draculaura driving away from the school in Draculauras new car, and splashing mud on Valentine and Toralei.Laura Bailey - Lagoona BlueOgie Banks - Clawd WolfCam Clarke - Heath Burns, Mr. Rotter, Hep Clouds, Valentines MotherDebi Derryberry - DraculauraErin Fitzgerald - Abby Bominable, C.A.
