Guy spun around. He saw Karma, the Troll who loved nature more than any other Troll. She had leaves and sticks wound into her green hair, and she wore a skirt the color of sunshine.

“What did you say?” Guy asked.

“I said I saw something,” Karma repeated. “Something that makes me think maybe the rainbows were taken!”

The little Trolls, Poppy, and Guy gasped. Who would take rainbows on the day of the Rainbow Rave? What a terrible thought!

Poppy rushed over to Karma. “What did you see, Karma? Tell us!”

“Well,” she began, “early this morning, just as the sun was coming up, I was walking in the woods, when—”

FWEE FWEE DEE DEE DWEEEE FWEE DOODLY DOOOO! Suddenly, loud music drowned out Karma’s story. The Trolls looked around to see where it was coming from. Cooper strolled up to the group, blowing into his harmonica. FWEE DOODLY DEEDLE DEEE!

“COOPER!” Poppy shouted, startling the four-legged Troll with the long neck. He stopped playing his harmonica.

“Oh, hi, Poppy! Hi, Guy Diamond! Hi, Karma! Happy Rainbow Rave! I was just practicing a new song I wrote for our celebration. It’s called ‘Rainbows Are the Rainbowiest Bows Made out of Rain!’ ” Cooper said. He looked around conspiratorially, then whispered, “It’s about rainbows.”

“That’s wonderful, Cooper,” Poppy said, “but in case you haven’t noticed, there aren’t any rainbows in the sky.”

“Really?” Cooper said, surprised. “I was too busy working on my new song to check out the sky.” He looked up, craning his long neck all around. Then he looked back at his fellow Trolls. “You’re right! No rainbows! On the day of the Rainbow Rave! What happened to them?”

Guy shrugged. “We don’t know, Cooper. But Karma saw something this morning that makes her think somebody took the rainbows!”

Cooper’s eyes grew wide. “Took?” He turned to Karma. “What was it, Karma? What did you see? WHY WON’T YOU TELL US?”

Leif tugged on Cooper’s leg. “Excuse me, Mr. Cooper, but I can explain. Ms. Karma was about to tell us what she saw when you came in playing your harmonica. Your music drowned her out, so she stopped speaking. Now that you’ve finished playing, at least for the moment, she’ll be able to resume her fascinating story.”

Everyone stared at the little Troll.

Cooper bent his long neck down until his head was close to the clever young Troll’s face. “You are very smart! Thank you for that excellent explanation,” Cooper told him.

“You’re welcome,” said Leif. “I liked your song.”

“Thank you!” Cooper said. “It’s a work in progress.” He turned to Karma, who had picked a flower and was tying it into her hair next to several others. “Karma, I’m sorry I interrupted your story. Please continue!”

Karma smiled. “Oh, no problem, Cooper! Anyway, as I was saying, early this morning, just as the sun was coming up, I was walking in the woods, when—”

Branch came running up. “Did someone say something about the rainbows being stolen? That’s GOTTA be part of a big conspiracy, right? What’d I tell you, Guy? CONSPIRACY!”

“Where? WHERE?” Cooper asked, wheeling around, afraid a big, mean conspiracy was about to jump on him.

Poppy held her hands up and patted the air. “Okay, everybody,” she said in a soothing voice. “Let’s all just take a deep breath, calm down, and listen to what Karma has to say. Karma?”

Karma was now down on all fours, staring at a tiny critter she’d noticed digging a hole in the ground. She looked up. “Hmm?” she said. “Oh, right! My story!” She stood up, not bothering to brush the dirt off her hands and knees. “Okay! As I was saying—early this morning, just as the sun was coming up, I was walking in the woods. I love that time of day, when all the critters are waking up, and stretching, and starting to sing.”

The other Trolls nodded. Though some of them liked to sleep late, they still knew what Karma was talking about. They all liked the sounds of nature first thing in the morning.

Karma fiddled with a stick in her hair. “I thought maybe I’d find some special flowers to put in my hair. And some sticks. And rocks. Maybe a little dirt.”

Some of the young Trolls looked puzzled. They thought they were supposed to keep their hair really clean so it would shine in the light. They’d never heard of putting dirt in their hair. A couple of them made mental notes to try it later.

“I’d found some flowers that I liked and was thinking about heading back into the village,” Karma continued. “But then I saw something through the trees. It was just a quick glimpse, but I’m pretty sure I saw someone hurrying away, dragging a bunch of rainbows!”

Branch frowned. “Are you sure you saw just one Troll? Not a group of Trolls? Like in a conspiracy? Or was it something other than a Troll?”

Karma thought for a moment, then shook her head. “Nope. Not a group. A someone. But there were lots of rainbows!”

Guy Diamond felt sure that Karma had seen a rainbow thief. If they could just catch the thief, maybe they could get the rainbows back and the Rainbow Rave would be saved! “What did this someone look like?” he asked urgently.

Karma twirled some of her green hair around a finger. “Well, like I said, it was just a glimpse. And he was partially blocked by all the rainbows he was dragging.”

“But it was a he?” Poppy said. “A guy took the rainbows?”

“I think so,” Karma said, nodding slowly.

“Let’s start with the most important thing,” Poppy suggested. “What was his hair like?”

“I’m not sure he had hair,” Karma answered.

They all gasped. No hair?

“I guess he might have had hair,” Karma went on. “I didn’t really get a good look at him through the trees.”

“Well, if he did have hair,” Poppy said, “what color was it?”

Karma thought a moment. “Um, white. But it wasn’t hair, exactly. More like…puffs.”

“White puffs?” Branch said, puzzled. “Wait a minute….Did this guy have skinny arms and legs? With a fluffy body? Striped gym socks with no shoes?”

“Yes!” Karma agreed, nodding. “He did!”

Branch and Guy turned to each other. “Cloud Guy!” they said at the same time.

“But why would Cloud Guy steal all the rainbows?” Poppy asked.

That was a good question. Guy Diamond had no idea why Cloud Guy would steal the rainbows and ruin the Trolls’ Rainbow Rave.

But he intended to find out.
