Evan leaned out into the darkness. A gust of cold wind made him shiver.
“Andy — what are you doing here?” he cried out.
“Get dressed,” Andy ordered. “Hurry, Evan. I have to show you something.”
“Huh?” He glanced back at Kermit’s clock radio. “It’s almost midnight!”
Andy raised a finger to her lips. “Sssshhhh. Hurry. Get dressed. I think you’ll want to see this.”
She held up a can. A blue plastic can.
Evan groaned. “You really came here in the middle of the night for another joke? Give me a break, Andy. What’s going to spring out at me this time?”
But then he saw the serious expression on Andy’s face.
“It isn’t a joke — is it?” he whispered.
She shook her head.
“It’s Monster Blood — right?” Evan demanded.
Andy nodded. “I think so. The can — it looks the same.”
Evan spun away from the window. He pulled on jeans and a sweatshirt right over his pajamas. His hands trembled as he tied his shoes.
He grabbed his down jacket from the closet. And climbed out the window.
“I was dreaming about Monster Blood,” he told Andy.
She bit her bottom lip. “This isn’t a dream,” she replied quietly.
Evan shivered. It was a cold, clear night.
Andy wore her magenta windbreaker and a pair of silvery leggings. She had a red wool ski cap pulled down over her short brown hair.
She raised the plastic can to Evan. “I think it’s the real thing. I hurried over as soon as I was sure my parents were asleep.”
“Where did you get it?” he whispered.
“Behind the lab on Peachtree where my dad works. We were picking him up before dinner. I was waiting in the parking lot behind the lab. I found this in a whole pile of stuff.”
“You didn’t open it — did you?” Evan demanded.
“No way,” she replied. She tried to hand him the can. But he waved it away.
“I don’t want it,” Evan told her. “Why did you bring it over here?”
Andy shrugged. “I thought after this afternoon, you might want to pay Conan back for being such a big jerk.”
“Yes, I do want to pay Conan back,” Evan admitted.
“So use the Monster Blood,” Andy urged. “You can put a little of it in his lunch at school. You can—”
“No way!” Evan cried. “Conan is already a mountain! I don’t want to make him any BIGGER!”
The light faded from Andy’s dark eyes. “I guess you’re right. But we could put Monster Blood in his bed. Or—”
“Stop!” Evan ordered. “It’s too dangerous. I don’t want to use Monster Blood on Conan. Kermit and I have another plan for Conan. A really good plan.”
“What is it?” Andy demanded eagerly.
“I’ll tell you as soon as you get rid of the Monster Blood,” Evan told her. “I really don’t want that stuff around. Go hide it someplace where no one will ever find it.”
“But, Evan—” Andy protested.
Evan didn’t let her finish. “You know what will happen if that can gets opened,” he said firmly. “It will bubble up. And it will grow and grow, and we won’t be able to stop it.”
“Okay, okay.” Andy rolled her eyes. “I’ll take it home. I’ll find a good hiding place.”
“Promise?” Evan demanded, eyeing her sharply.
“Promise,” she repeated, raising her right hand.
“Hey — what’s that?” a voice called from behind them.
Evan spun around and saw Kermit scramble out the open window.
Kermit grabbed the blue can from Andy’s hand.
“Cool!” he cried. “Monster Blood! Is it real?”
He didn’t wait for an answer.
He gripped the can tightly — and pulled off the lid.

“No! Don’t do that!” Evan screamed.
Too late.
“Close it up!” Evan cried frantically. “Close the can — quick!”
Kermit stood staring into the open can. “It’s too dark. I can’t see anything.”
“Give me that!” Evan ordered. He leaped forward and tried to swipe the can away.
He grabbed the can — but knocked the lid from Kermit’s hand.
Kermit made a wild grab for the lid. But a gust of wind blew it out of his reach.
As Evan gaped in horror, the wind lifted the plastic lid… lifted it over their heads.
“Noooooo!” He let out a long wail as the lid spun crazily above them. He made a wild grab. Another. Missed.
The wind carried the lid up to the slanted roof of the house. It hit the shingles. Slid down a few feet. And came to a rest in the metal rain gutter.
“I don’t believe this,” Evan muttered.
“I’ll get the ladder from the garage,” Kermit offered. He took off across the dew-wet grass.
“Hurry!” Evan cried.
“The Monster Blood — it’s moving!” Andy exclaimed, pointing with a trembling finger.
Evan gazed down at the can gripped tightly in his hand. He couldn’t really see inside. Dark clouds had drifted over the moon, blocking out the light.
Evan brought the can close to his face. And gasped.
“Andy — it’s blue!”
“Huh?” She pressed close to him. Their heads banged as they both eagerly stared into the can.
Yes. The thick glop inside the can was blue — not green.
It made a sick plopping sound as it rolled from side to side, like an ocean wave.
“It — it’s trying to get out!” Andy stammered.
“Hurry, Kermit!” Evan called.
Kermit came running from the garage, an aluminum ladder tilted over one shoulder.
“Why is it blue?” Andy asked.
The thick goo lapped at the side of the can. As Evan stared in horror, it splashed up over the top.
“Kermit — please hurry! Get the lid!” he cried.
Kermit propped the ladder against the side of the house. Then he turned back to them. “Someone else has to climb up,” he called.
“Just do it!” Evan screamed frantically. “The stuff is spilling out over the top!”
“But I’m afraid of heights!” Kermit declared.
Evan rolled his eyes. “It isn’t that high. Just climb up, and—”
“I can’t!” Kermit whined. “Really!”
“I’ll do it.” Andy ran to the ladder. Kermit held it steady for her.
Evan watched her scramble up. The Monster Blood bobbed and plopped in the can. The clouds rolled away from the moon. It was definitely bright blue, Evan saw.
And definitely trying to raise itself out of the can.
Andy climbed up to the gutter. Holding the ladder with her right hand, she reached out to the lid with her free hand.
Reached… reached…
And the wind blew the lid from the gutter.
“Noooo—!” Andy screamed. She grabbed for it.
Lost her balance.
Grabbed the sides of the ladder with both hands.
The lid spun crazily in the air. Then it swooped down to the grass.
“I’ve got it!” Kermit cried. He dove for it and grabbed it in one hand.
“Yes!” Evan cried happily. “Put it on the can — quick!”
Andy carefully lowered herself rung by rung.
She reached the ground, turned, breathing hard, and hurried back to Evan.
Kermit came running over with the lid.
But before he reached Evan, a voice rang out from the yard across from his.
“Hey — what’s going on?”
Evan looked up to see Conan running across the grass.
“Oh, no!” Evan moaned, and the Monster Blood can fell out of his hand.
13
With a gasp, Evan bent to pick up the can.
Had the blue Monster Blood spilled out?
No.
He lifted it carefully, holding one hand over the open top.
Conan stopped at the edge of the yard. “What are you three babies doing out so late?” he demanded. “I’ll tell your mommies!”
“Give us a break, Conan,” Andy called. “We’re not bothering you!”
“Your face is bothering me!” Conan shot back. Then his eyes fell on the can in Evan’s hand. “What’s that?”
