"Psych" -- Dule Hill as Gus Guster, James Roday as Shawn Spencer

Bust out your sleeping bag and your best pineapple-flavored snacks, because USA's "Psych" stars are hosting a viewer's choice marathon and on-air slumber party February 15.

Beginning at midnight and airing through February 16 at 6 AM, "Psych" stars James Roday, Dulé Hill, Maggie Lawson, and Tim Omundson will host the real-time marathon party, in which fans of the quirky, pop-culture-obsessed comedy watch at home while sharing the screen with the cast.

The cast has planned skits just for the slumber party event, which will also include an on-air Twitter ticker (hashtag: #PSYCHSlumberParty), videos, second-screen trivia, GetGlue stickers, and prize giveaways. Fans can keep updated on the evening's activities at the PSYCHVille website.

Fans who want an extra shot at "Psych"-themed goodies should also tune in earlier, at 10 PM, for the "Pre-Party Prize-a-Thon," when USA will give away 120 prizes in 120 minutes. Roday and Hill will also make prank phone calls to viewers before and during the all-night slumber soiree, and the Pineapple Code Word Hunt -- during which pineapple code words will be shown on air each hour of the marathon -- will lead viewers to an online game where they could win a trip to the set of "Psych."

The fan event is a celebration of Season 7 of USA Network's longest-running series, which premieres February 27, and will include a two-hour musical episode, "Clue" and "The Blair Witch Project" homage episodes, and guest appearances by Jeffrey Tambor, Martin Mull, Christopher Lloyd, Anthony Michael Hall, and Parminder Nagra, who will play the love interest of Hill's Gus.

The "Psych" Slumber Party Marathon premieres February 15 at midnight on USA.

"Psych" Season 7 premieres Feb. 27 at 10 PM on USA.
