Joy, Sadness, and Bing Bong rushed off the stage of Riley’s dream at Dream Productions, leaving Jangles behind as he smashed up the sets and everything in his path with his giant mallet. They hurried toward the Train of Thought.

The train was moving! The three leapt aboard the very last car.

“Ha ha!” Joy said. “We made it!” They laughed and celebrated. She grabbed Sadness and swung her around. “Guess who’s on their way to Headquarters?” Joy sang.

“We are!” said Sadness.

Back at Headquarters, Anger and Disgust stumbled out of the break room, disheveled and barely awake. “What is going on?” asked Disgust.

“He did it again,” said Anger, gesturing to Fear trembling beneath the console.

“We were at school, and we were naked, and there was a dog, and his back half was chasing him…” Fear rambled, recalling Riley’s dream.

Anger was reaching his limit. “It was a DREAM! This is ridiculous, we can’t even get a good night’s sleep anymore. Time to take action.”

Anger stomped off and retrieved the idea he had held up earlier. He stood at the console, ready to plug it in. “Who’s with me?” He looked at Fear, who was still recovering and unable to utter a word. Then he looked at Disgust and waited for a response.

“Yeah, let’s do it,” said Disgust finally.

Anger plugged the lightbulb-shaped idea into the console.

Inside her bedroom, Riley’s expression changed. She pulled out her laptop.

“She took it. There’s no turning back,” said Anger.

“So, how’re we gonna get to Minnesota from here?” Disgust asked.

“Well, why don’t we go to the elephant lot and rent an elephant?” Anger asked sarcastically. Then he yelled, “We’re taking the bus!”

Riley pulled up the Greyhound bus website and began to look at the schedule for buses to Minnesota.

“A ticket costs money,” said Disgust. “How do we get money?”

“Mom’s purse,” Anger said casually.

Disgust gasped. “You wouldn’t.”

“Oh, but I would,” said Anger. “Where was it we saw it last?”

He punched up a memory and the Tripledent singers came on again, singing the theme song.

“NOOOO!” Anger slammed down on the console, ejecting the memory. Then he remembered that Mom’s purse was downstairs somewhere. “Mom and Dad got us into this mess,” Anger said. “They can pay to get us out.”

Inside the train, Joy, Bing Bong, and Sadness were happily speeding along. Joy looked at Sadness. “Hey, that was a good idea,” she said. “About scaring Riley awake.”

“Really?” Sadness said, sounding surprised.

“Nice work.”

Sadness brightened a little as Joy exhaled, feeling relieved. “I can’t wait to get the old Riley back,” she said. “As soon as we get there, I’m going to fix this whole mess.”

Bing Bong had found a box of memories and was looking through them. He discovered a recent memory and saw that Riley was much older than he had thought. “Whoa,” he said. “Is this Riley?”

Joy took the memory to get a closer look. She nodded.

“She’s so big now,” Bing Bong said. “She won’t fit in my rocket. How’re we gonna get to the moon?”

Joy recognized the memory. “Oh, it’s that time in the twisty tree, remember? The hockey team showed up and Mom and Dad were there cheering…Look at her, having fun and laughing. It’s my favorite.” Joy sat back down, beside Sadness.

“I love that one, too,” said Sadness.

Joy couldn’t believe it! Sadness actually liked a happy memory. “Atta girl!” she said. “Now you’re getting it!”

Sadness stared at the memory. “Yeah,” she said, remembering. “It was the day the Prairie Dogs lost the big playoff game. Riley missed the winning shot. She felt awful. She wanted to quit.”

Joy’s face fell. Sadness had started out so positive. “Sorry,” Sadness apologized. “I went sad again, didn’t I?”

“I’ll tell you what,” Joy said. “We’ll keep working on that when we get back. Okay?”

Sadness smiled. “Okay.”

Meanwhile, Riley sneaked downstairs to find her mom’s purse. Mom was in the kitchen on the phone, talking to the moving company, so Riley was able to find the purse and slip the credit card out quietly. She put it in her pocket and crept back upstairs without Mom noticing.

Joy looked wistfully out the train window. All of a sudden a loud BOOM broke the spell. “Honesty Island!” Joy shrieked.

The train tracks they were on began to sway as Honesty Island started to collapse below them. Joy, Sadness, and Bing Bong were jostled back and forth. Screaming, they fell as the train started to tumble, the tracks slipping away with the collapsing island.

The train crashed onto the side of a cliff and began to tip over as mind workers rushed on board.

“Let’s go! Move it! Move it!” the workers shouted, trying to get everyone off safely.

Joy, Sadness, and Bing Bong jumped to land just in time as the train plummeted into the Memory Dump below. Joy couldn’t believe it. “That was our way home!” she said. “We lost another island….What is happening?”

“Haven’t you heard?” asked a worker. “Riley is running away.”
