Here a another Christmas Karaoke did time it's Popplio and
she sing a Blue Christmas

Popplio: I'll have a blue Christmas without you
I'll be so blue just thinking about you
Decorations of red on a green Christmas tree
Won't be the same dear, if you're not here with me
And when those blue snowflakes start falling
That's when those blue memories start calling
You'll be doing all right
With your Christmas of white
But I'll have a blue, blue, blue, blue Christmas
You'll be doing alright
With your christmas of white
But I'll have a blue, blue, blue, blue Christmas
You'll be doing all right
With your Christmas of white

note the lyric don't belong to me and Popplio belong to Pokemon
