Ah, the nostalgia of the icy Club Penguin island. What we all wouldn’t give to be kids again just to beg our parents for a membership and to meet our virtual girlfriends/boyfriends at the Pizza Parlor just one more time.
The “Cool in the Cold” design is an album cover for the hit Cool in the Cold, featuing the ice island of Club Penguin with penguins milling about and an igloo.

"It’s cool, cool, cool, out in the cold

And it’s fun, fun, fun, covered in snow

Everyone’s here, it’s that time of the year, oh

It’s cool in the cold"
