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."

"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."

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

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

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

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

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

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

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

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

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

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

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.

小宏从床底下把那件连帽衫拽了出来。他坐起来，翻了翻衣服兜。“我的微型机器人！”他一边说一边拿出了一个。那正是他做展示时用的那个。不知怎么的，它还在那里颤动。“这不对啊。”

“从小男孩成长为男子汉往往都要经历令人困惑的青春期。”

“不，”小宏回答道。他把微型机器人放进一个玻璃培养皿里面，用盖子盖起来。那个微型机器人还是不停地颤动着。“它正被其他微型机器人所吸引。”他自言自语道。“但它们全部被那场大火毁掉了呀。这蠢东西肯定是坏掉了。”

他把培养皿扔在桌子上，抓起超能机器人，转过身背对着大白和微型机器人。

大白低头看着培养皿。微型机器人一直在碰撞着培养皿的一侧。

大白说：“你的微型机器人想要去一个地方。”

小宏恼火地盯着天花板答道：“哦，是吗？那你为什么不帮我找找它想去哪儿呢？”

大白点点头，拿起玻璃皿说道：“这样做会稳定你的青春期情绪波动吗？”

“嗯哼，那还用说，”小宏说道，他希望大白能离开，让他安静一会儿。

小宏想让大白自己考虑这个问题。可是，大白却出门了。小宏还没发现，这个大机器人就消失了！

听到外面汽车的鸣笛声，小宏朝窗外看了看，发现大白走进车流中，车辆发出尖锐刺耳的声音，纷纷避让，以免撞到他。小宏匆匆穿上连帽衫冲出了自己的房间。他下楼下到一半时，卡斯阿姨看到了他。

“小宏！”她说，“你穿戴好起来啦。太好了！你是要去学校登记吗？”

小宏打着滑停了下来，努力使自己看起来很自然。“呃，对。是的，你说对了，我这就是要去注册课程。”

“你确定你已经准备好了吗？”卡斯阿姨问道。

小宏听到外面响起的越来越多的喇叭鸣笛声，便回答道：“准备好了。”

“好啊，今晚来顿特别的晚餐！我迅速做些鸡翅，再配上些能把咱们的脸辣到麻掉的辣酱怎么样？”

小宏快速地点点头。“听起来很赞啊，”他说道。卡斯阿姨拥抱他时，他正打算要跑掉。小宏回抱了一下阿姨，就冲出了门。

他沿着街道跑着，可是哪里都没有大白的影子。他跟着汽车的紧急刹车声和轮胎发出的刺耳摩擦声寻找着，终于看见了那个白色大机器人的身影。他正在一辆电缆车的后面。

“大白！”小宏喊道。
