Well there's snow on the groundThe day looks too hot for Phineas and Ferb to do anything, until their dad gives them his snowcone machine. That gives Phineas an idea to make it snow that day, since snow in winter is when it's too cold to enjoy it.Meanwhile, Dr. Doofenshmirtz plans on using loads of laser pointers to melt chocolate, collect it, and then reform it into his image, so that people will like him more.
There's sleigh-bells all around
But the sun's beating down
'Cause it's S'Winter
