"Ugh…" Phineas moaned from next to Candace underneath the oak tree in the backyard. Candace looked over to her left and was surprised to see Phineas and Ferb literally standing on their heads.
"What's up with you two?" Candace asked as Lawrence walked out of the garage holding a box.
"It's too hot to think, we don't know what to do." Phineas complained crossing his arms over his chest, still sitting on his head.
"Why don't you guys go sit in the air conditioning?" Candace asked standing up. "For that matter, why don't I? I'm burning up out here!"
As Candace entered the house she heard Lawrence say something about snow cones. Kicking her shoes off at her door Candace entered her bedroom and immediately called Stacy. After complaining about cheerleaders for several minutes Candace's room was suddenly covered in darkness.
"Hey! Who turned out the sun?" Candace asked walking over to her window covered in snow. "Hmm. Probably not a good idea to open this." Walking downstairs Candace entered the backyard to find a literal mountain of snow.
"You like it?" Phineas asked walking next to her. "We call it S'Winter."
As Phineas, Ferb, Isabella and a few fireside girls broke out into song Candace walked back into the house and put on her winter boots. After exiting the house, she saw Jeremy getting ready to board a ski lift.
"Hi, Jeremy." Candace said nervously as she walked up to him.
"Hey, Candace. You want to go skiing?" Jeremy asked gesturing to the ski lift.
"Oh, I'd love to, but, uh, but I am so afraid of heights." Candace said glumly as someone walked up to them wearing heavy winter gear.
"Bummer. Well, see you later, then." Jeremy said turning towards the ski lift and seeing someone he knows boarding. "Hey, D. D., wait up!"
"D. D.?" Candace gasped as she pulled out her phone and called Stacy immediately. "Stacy? Who's D. D.? A Swedish exchange student?! I gotta go." Just as Candace was about to hang up Stacy shouted for her to stop. "Oh, D. D. is a guy… I knew that…"
Candace walked back inside and plopped down on the couch. After flipping through random channels for countless minutes she heard her parents' car pull up. Walking out front she saw her parents carrying a giant cuckoo clock.
"Candace why are you wearing your winter boots? You know what, never mind that. Can you get the door?" Lawrence said strain in his voice as he and Linda carried the clock towards the house.
"Sure thing!" Candace said holding the door open as they walked through.
"Well honey, what do you think?" Lawrence asked Linda as they placed the clock on the wall.
"It's nice." Linda said as Phineas and Ferb entered the house carrying snow cones.
"Hello boys, how'd you enjoy the snow cone machine?" Lawrence asked
"It was awesome, we made S'Winter!" Phineas said as he approached them. "Anybody want a snow cone?"
"I'll take a snow cone, it's hot out there today." Linda said accepting the crushed ice covered in blue carbs.
"Me too." Lawrence said also accepting the icy treat.
"Candace?" Phineas said temptingly waggling the ice cone. Candace was reaching towards the cone when the cuckoo clock suddenly went off and knocked the snow cone out of Phineas' hand before smashing through the window.
"Well… that was unexpected." Ferb said licking his snow cone.
