"No," Hiro replied. He put the microbot into a glass petri dish and placed a lid on top. The small bot continued to vibrate. "This thing's attracted to the other microbots," he said to himself. "But they were all destroyed in the fire. Dumb thing must be broken."

Hiro pulled the hoodie out from under his bed. He sat up and quickly searched the pockets. "My microbot!" he said, pulling one out. It was the bot he'd used in his demonstration, and somehow, it was still vibrating. "This doesn't make sense."

"Puberty can often be a confusing time for a young adolescent flowering into manhood."

Baymax looked down at the petri dish. The microbot kept banging against one side of the glass.

He tossed the petri dish on his desk and grabbed Megabot, turning his back on Baymax and the microbot.

Baymax said, "Your tiny robot is trying to go somewhere."

Baymax nodded and picked up the petri dish. "Would it stabilize your pubescent mood swings?"

Exasperated, Hiro stared up at the ceiling. "Oh, yeah? Why don't you find out where it's trying to go?"

"Hiro!" she said. "You're up and dressed. That's great! Are you registering for school?"

"Okay, special dinner tonight! I'll whip up some chicken wings, you know, with the hot sauce that makes our faces numb?"

"Uh-hmm, absolutely," Hiro said, hoping Baymax would finally leave him in peace.

Hiro expected Baymax to ponder the problem. Instead he headed out the door! Before Hiro knew it, the big robot was gone!

Hearing cars honking outside, Hiro looked out the window and saw Baymax heading into traffic, cars screeching to avoid hitting him. He threw on his hoodie and dashed out of his room. He was halfway down the stairs when Aunt Cass saw him.

Hiro heard the sound of more horns honking outside. "So ready," Hiro replied.

"Are you sure you're ready?" Aunt Cass asked.

Hiro nodded quickly. "Sounds good," he said. He was about to run off when Aunt Cass gave him a big hug. Hiro hugged her back, then dodged out the door.

He ran down the street, but there was no sign of Baymax anywhere. He followed the sound of cars hitting the brakes and tires screeching until he finally got a glimpse of the big white robot. He was on the back of a cable car.

"Baymax!" Hiro yelled.

Hiro skidded to a stop and tried to sound casual. "Uh, yeah. That's it. Exactly. Registering for classes."
