Halloween Havoc

A/N: Don't own the Lorax or the Addams Family.  However, I do own Kat and any other original characters in this fanfic.  This fanfic is for Once-ler/OC week on deviantart.  I picked day six and day seven.  This takes place when Kat and Once-ler are both rich and living together.  I'd like to thank Mircosedy from fanfiction.net for beta-reading.  I'd also like to thank bloodrosered for PMing with me on fanfiction.net about how I can push the limits of a T rated fanfic.

"You think Mr. D'Amico's secretly a criminal mob boss and that's why he's so rich?" Kat asked as she looked out the window to see the large buildings and the trees in the background slowly decreasing in numbers.

"The guy comes from four generations of wealth and inherited a well-to-do soda factory. I don't think he needs to get involved with crime," Once-ler said doubtfully.

"Not every rich man's an outstanding citizen. Maybe he hooked up with the mafia so he could remain the top soda entrepreneur in business," Kat pondered as she turned to Once-ler with a mischievous grin. "Or maybe he's the head of the D'Amico crime family and he's using his soda business to embezzle funds."

Once-ler laughed. "Save your creative energy for your writing, Cara Bella."

"I can't help it, when the muse strikes me, I simply must create, Mon Cheri," Kat said, changing her tone to be icy yet seductive.

"That's french!" Once-ler said excitedly. Then he held Kat's hand and kissed it with a fiery passion. Kat leaned against the soft black leather seat, enjoying Once-ler's touch.

Once-ler stopped as soon as he heard the door open. It was Isabella with her fake sweet smile.

"Kitty, will you scoot down in the middle?" she asked with fake politeness.

"Kat," Kat told her as she scooted near Once-ler on the leather black seats.

Isabella took the seat on Kat's left as Aunt Grizelda, Uncle Ubb, Brett and Chet took their places across from them.

"I love your costume, Kitty!" Isabella said as she looked at Kat's Morticia costume. "A bizarre harlot who uses her feminine wiles to wrap her husband around her finger, very suiting."

"Burn!" either Brett or Chet exclaimed (Kat never could tell them apart) as everyone laughed, Aunt Grizelda's being the meanest. The only one who didn't find this funny was Once-ler.

"It's Kat," she, once again, corrected out of impulse and then looked at Isabella's costume. "You went with Glinda the Good Witch of the North?"

"Yes, isn't it lovely?!" Isabella exclaimed.

"I thought you would've gone with the Wicked Witch of the West," Kat said nonchanlantly.

Isabella looked horrified as everyone (save for Once-ler and Aunt Grizelda) laughed at Kat's comment. Then her fake smile returned.

"Kitty, not everyone on Halloween wants to dress up as a monster," Isabella condescendingly explained. "Some women actually prefer to look nice for the night."

Once-ler was about to come to Kat's defense until she gave him a look that told him she could handle this.

"I can't help it, whenever I look at you, I think 'wicked witch,'" Kat responded with a smirk. "Don't know why."

Before anyone could reply, the limo stopped outside of D'Amico's mansion. As the Once-ler family stepped out of the limo, Kat saw the mansion in all its glory. The mansion was huge with gray bricks, various windows and a large wooden door complete with a second floor balcony.
