Kaa and Bianca were at Bianca's house on Christmas Day. Christmas music was playing and Bianca was nearly done with her presents.
Kaa was slithering into Bianca's Christmas stocking. "Isss thisss my presssent?" he wondered. "It feelsss warm enough."
Bianca giggled. "Silly Kaa, it's a Christmas stocking. It's for smaller presents like pencils and candy. I did get you something, though." She went up to her room and got a box. She brought it downstairs and gave it to Kaa. "Here."
Kaa unwrapped it with his mouth and tail. Bianca helped out a bit with her hands. When the box was opened, Kaa blinked. "What'sss thisss?"
"It's a pet sweater," Bianca explained helpfully, holding up the bottom hole. "Stick your head in here."
Kaa slid his head in. It took a couple of tries for him to find the head hole as he went through both sleeves first. Finally, when Kaa stuck his head out of the head hole, Bianca smiled and said, "There you go!"
Meanwhile, Kaa's evil brother, Ben, was hiding in the basement, trying to hibernate for the winter. Unfortunately, all the Christmas carols and conversation were keeping him up. "I'll ssshow thossse ssstupid humansss," he cursed. He slid into the ventilation shaft, careful not to blunder into anything bladed (like a fan) or hot (like a heater).
Later, Bianca was up in her room with Kaa. They were playing with Bianca's presents. Just then, Bianca heard a noise. "Hmm? Wait right there, Kaa. I think something's stuck in the vent." I went over to the vent.
She found herself staring at something colorful, like a pair of shiny gems. The psychedelic colors dazzled and confused her mind. "Let me out," said a voice.
Bianca dully felt around for something to unscrew the vent with. She found a ruler and started loosening the screws with its thinnest part. When the vent was halfway open, Ben slithered out. He began coiling around Bianca...
And got a headbutt from Kaa, knocking him loose. Kaa turned to face Bianca and stared into her eyes. "Bianca, sssnap out of it!" he commanded, counter-hypnotizing her.
Bianca snapped out of it just as Ben lunged at Kaa. Now free from the coils, Bianca thought quickly. She opened the window of her bedroom and let the cold air in. Being snakes, Kaa and Ben were cold-blooded, and the sudden drop in air temperature caused them to lose consciousness.
Bianca pulled Ben off Kaa and pushed the evil snake out the window, coil by coil, so that his fall to the ground was a gradual one. "And stay out!" she shouted, slamming the window shut.
It took Kaa a few minutes to revive as the heater kicked back in. "Fassst thinking, Bianca," Kaa congratulated her when she explained the whole thing.
"Thanks for saving her," said Bianca.
"I love you, Bianca," said Kaa with a smile.
"I love you, too, Kaa," Bianca smiled back. "Merry Christmas." They kissed and hugged.
