Party Down South's biggest Louisianimal is getting ready to officially take himself off the market on the show's Oct. 15 episode.

Raven & Bradley Are Having A Girl!

Lyle knows he has found the "Bou" to his "dreaux" in girlfriend Santana and is getting ready to take a huge step and propose to her-but he's going to need help from Murray, Walt, Daddy, Mattie, Hannah, Tiffany and Lauren if his plans are going to be a success.

Not only will he enlist the help of the guys in picking out the perfect ring and get the girls to distract Santana with a day at the nail salon, but he will also ask his roommates to get everything ready for the proposal back at the house when he takes her out for a romantic dinner. But in a preview clip for the episode, the stress could be getting to the gang.

The Miami Trip Takes A Scary Turn When Mattie Goes Missing

"We have to put all the flowers, make sure all the lights are hung," Mattie says.

Among the tasks the gang has to complete before the couple returns is prepare a nice dessert for them, light candles and string lights in the backyard, tape the ring under the table so it remains hidden, and arrange flower petals on Lyle's bed. And though they want Boudreaux to be happy, the growing task list does begin to stress them out.

"This is a lot of pressure on me right now," Daddy says in the clip.

But, the gang manages to pull it together in time-and Lyle does work through his nerves to ask Santana to marry him.

"Spend the rest of your life with me, forever and always," he says to her in the clip as he gets down on one knee and presents her with the ring.
