Disclaimer: I don't own Hot Wheels: Battle Force Five.
Also, I can only remember the first five from the first day of Christmas and this was basically like someone else's BF5 Guest Data Draft, which is better than this version.
"Ahem…on the twelfth day of Christmas, the subspecies gave to me," Kalus sung. Sage managed to convince both Sark and Vandals to join their secret Santa party that the Battle Force Five gang was throwing. Spinner just thought it would be great for them to sing what they all got, starting with Kalus. "Twelve severed Sark heads!"
"Eleven meat-discs to eat!" Sever continued, munching on some pizza.
"Ten bouncing balls," Hatch added, soon giggling like an idiot watching the soccer balls bounced.
"Nine ways to snap a neck, eight pieces of a body," Krocomodo sang, everyone paling and looking around for any missing members.
"Seven bunches of bananas, six deadly jokes," Grimian sang before everyone heard some honking from behind the Vandals. They all looked in that direction and their jaws dropped.
"I'M, HIJACKING, YOUR VEHICLES!" Aura sang in part of the fifth day, driving off with all the Vandal's vehicles. Kalus and his group ran after her as the others laughed at their misfortune.
"Four awesome friends!" Zug/Buzz said, grinning at Selia, Stanford, Zemerik and Sage.
"Three battle squads," Selia sang.
"Two battle keys," Vert sang along.
"And a kiss under the Christmas tree," Marik said, giving Sage a quick kiss. "…Merry Christmas," he said, his cheeks a deep red.
