SpongeBob and Patrick race to Sandy's treedome to hang out with her. However, the dome has a metal cover over it and a, "Keep Out", sign on the front door. In the entryway, they find a tv, which it turns on, and plays a video of Sandy dressed for bed, and eating acorns. The recording of Sandy explains that she's hibernating for the winter and asks for no one to disturb her. However, Patrick opens the door anyway to reveal that the dome's environment completely covered with snow.Then SpongeBob and Patrick quickly take delight in the snow, even being able to remove their water helmets because of the snow's moisture. Then they hear a strange noise from Sandy's treehouse, then they inside go to investigate. Then they discover that Sandy, is many times her original size, and sleeping soundly. At first, their gentle prodding, and poking do nothing to wake her from her dreams of catching the outlaws Dirty Dan and Pinhead Larry. Though, soon enough, their merrymaking takes its toll, and then Sandy suddenly wakes up, assaulting SpongeBob and Patrick in her sleepy stupor. Then she falls back to sleep into her bed. Then Patrick makes a pair of earmuffs from Patrick's belly button lint, and place over Sandy's ears to prevent Sandy from waking up.
Then SpongeBob and Patrick leave her room to continue playing in the snow. Then they pretend to be the outlaws from Sandy's dream, but then they start fighting over which one of them will play the part of being Dirty Dan. Then their roughhousing knocks Sandy's earmuffs off, allowing her to hear all the noise, and set upon them and attacks them in further half-asleep fury. Being battered and bruised with the winter storm growing more intense, SpongeBob and Patrick try to leave, but then they find that the door's frozen shut, leaving them trapped in the wintery treedome.
Unable to escape or survive in the cold weather, they go into Sandy's room and, throwing caution to the wind, rip off all her fur. With their new fur-lined winter attire, SpongeBob proclaims that now they're ready for the "longest, coldest winter ever!" However, winter immediately comes to an end, and then Sandy wakes up with her winter pounds shed. Then she's surprised to see SpongeBob and Patrick wearing her fur, but then she's initially confused, when she looks down and finds herself completely bald. Then SpongeBob and Patrick realize that ripping her fur off wasn't a good idea, and now they have to suffer the consequences.
She drinks lemonade with them, with their bodies wrapped around her to provide her new spring coat to keep her warm until her fur grows back, much to SpongeBob and Patrick's discomfort and dismay.
According to the audio commentary and in the storyboard, there is a deleted scene where Sandy's bed was hanging from the ceiling, and there was much more saliva/drool. Also stated in the audio commentary, the original title was "Survival of the Morons."
