Poinsettia:

By the time the pair stopped, they were right at the bottom of the hill. What immediately stood out to them were the lights to a greenhouse, used to grow what looked like poinsettias. Karen only vaguely knew what they were, given that her mother only bought them once every couple of years. Frosty, for all of his inexperienced opinion, thought they appeared rather nice-looking. However, there was still the matter of Karen needing a new heat source.

"It's got to be all warm and snug inside for those Christmas flowers that grow so beautiful. Let's go in."

At first, Karen's face fell.

"Oh, but, you will melt."

"Just a little. I'll only stay inside for a minute." He reassured, then tried for some humor. "Besides, I've been meaning to take off a little weight anyway."

He almost regretted it when he walked in to feel what seemed like a wall of heat ram him head-on. Sighing somewhat, and heartened when Karen stopped shivering, he couldn't help but make a hapless remark about the situation.

"Stay in here much longer and I'll really make a splash in the world."

Hitting on the mark, Karen gave a small giggle, prompting a small grin from the snowman in return.

However, the tender moment was cut short when the door to the greenhouse suddenly slammed, and Frosty stared at the triumphant grin of Professor Hinkle.

"Now I've got you! And the minute you're all melted the hat will be mine!"

The somewhat crazy laughter that followed did not help the silicon weight of dread that dropped through the mood like a rock through wet paper.
