Whirling Street Moscow/Think of the Warmest Things is a song sung by Luna to Leo in the episode You Froze My Shorts.
Lyrics
Whirling through the streets of Moscow
On a Russian sleigh
You've been cold all day
Shivering away
Here's a game to make you warmer
When the skies are grey
Let me lead the way
And soon everything'll be OK
Think about the warmest things in Russia
Moscow in July
Freshly toasted rye
Candle's yellow light
Burning through the night
A fire in the fireplace warming the air
A comforting hug from your favorite teddy bear
Thick fur hats and black felt boots
Cozy chats and hot pursuits
Think of the warmest things
Only the warmest things
That's how you beat the cold
