Eventually, dazed and achy, Arlo opened his eyes and looked around. His legs were still in the water, and his body was beached on a small sandbar. He was miles down the river and very far from home.

Some big logs were jammed together next to him, making sharp peaks that looked like angry teeth. His body throbbed with pain, each scrape and scratch burning as he breathed. He felt the bump on his head and shuddered.

As Arlo took in his surroundings, fear began to ripple through his body. "Momma!" Arlo cried. "Momma!" His voice echoed, ringing against the towering cliff walls that surrounded him. When he quieted the only other sound he could hear was the wind moving through the pine trees and the gurgles of the river washing over the rocks. He was completely alone.

Arlo tried to gather the strength to climb out and slowly rose to his feet. But the ground crumbled beneath his feet. He slipped and his jaw smacked against a boulder, jutting out. Arlo lay still, trying to catch his breath. He needed to figure out what to do next.

Arooowwwwh. A loud howl sounded, down into the canyon. He looked up toward the top of the cliff wall and saw... the boy from the trap! A burning anger boiled up inside of him. "You!" he yelled. "This is all your fault!"

Furious and fueled by his anger, Arlo propelled his body up the cliff to try and get to the boy. "I should have finished you off the first time."

The boy just sat on the edge of the cliff. Cocking his head this way and that, he watched curiously as Arlo clumsily made his way up the mountain. He was working hard and struggling for breath, but still managed to seek out a few choice words: "This is all your fault!" Arlo said.

The boy remained calm, sitting and watching. This made Arlo even angrier. He snapped. "Get over here!" he shouted.

Then the boy did something entirely unpredictable: he tried to climb on Arlo's face!

"Get away!" Arlo screamed. He repeated it over and over, harshly jerking his neck, and tossing the boy off. The boy turned and used his hind legs to kick dirt at Arlo's face. The dinosaur spit and coughed, trying to get the dust and dirt out of his mouth.

When Arlo finally managed to hoist himself up onto the cliff's edge, the boy had disappeared. "You better run!" Arlo called after him, threateningly.

Arlo took a deep breath and slumped. He looked around at his surroundings again. The wilderness around him seemed to be the whole world. He couldn't see an end to it. He spotted a high ridge off in the distance and thought if he could get up to the ridge, maybe he could see where home was. With no choice, no one to ask, and no other ideas, he started off, toward the ridge.

终于，阿乐睁开了眼睛，他环顾四周，感觉晕乎乎的，全身酸痛。他的双腿还浸在水里，身体却搁浅在一个小沙洲上。他已经顺着河流被冲到了离家几英里之外的地方。

他身旁有一些大原木，堆成尖锐的山峰，看起来就像愤怒的牙齿。他的身体在阵阵抽痛，伴随着呼吸，每一处擦伤和刮伤的地方就像火烧一样。他摸到头上肿了个包，身体不停地哆嗦。

阿乐看看周围，恐惧开始迅速传遍全身。“妈妈！”阿乐哭叫着，“妈妈！”他的声音受到四周高耸的崖壁的阻挡，回荡在悬崖间。当他平静下来，唯一能听到的就是风吹过松林的呼啸声和河流冲刷岩石的汩汩声。他孤身一人，无依无靠。

阿乐想用尽全身的力量从水里爬起来，他慢慢地抬起脚，但是脚下的地面坍塌了。他脚下一滑，下巴磕到了一块突出的巨石上。阿乐一动不动地躺在那里，竭力喘着气。他需要弄清楚下一步该怎么办。

啊哦！一声响亮的吼叫响起，传至峡谷。阿乐抬头望向峭壁上方，他看到了……那个从陷阱里逃跑的小男孩！顿时，他怒火中烧，他叫道：“你！都是你的错！”

阿乐暴怒，在怒气的刺激下，他爬上悬崖，努力想抓住那个小男孩。“我上次就该结果了你。”

小男孩坐在悬崖边上，摇头晃脑，好奇地看着阿乐笨拙地往山上爬。阿乐一边上气不接下气地奋力向上爬，一边想方设法措辞，责骂道：“这都是你的错！”

小男孩依旧很淡定，坐在那里看着他。这让阿乐愈发生气了，他怒不可遏地厉声喝道：“滚过来！”

接着，小男孩做出了完全出人意料的事：他试图爬到阿乐的脸上！

“滚开！”阿乐大叫道。他一遍一遍地重复着，用力甩脖子，把小男孩甩下来。小男孩转过身，用后腿往阿乐的脸上蹬土，弄得阿乐又吐又咳，想把嘴里的尘土和脏东西吐出来。

当阿乐终于成功爬上悬崖的时候，小男孩已经不见了。“你最好跑快点！”阿乐在后面颇具威胁地喊道。

阿乐深吸一口气，猛然瘫坐在地上。他又看了看四周，仿佛除了荒野还是荒野，看不到尽头。他发现远处有一个高高的山脊，心想：如果能爬上山脊，或许就能看到家在哪里。他别无选择，也没有人可以问，更没有其他的办法，只能启程朝山脊走去。
