还好我会游泳……
悠悠庆幸自己曾经学过游泳，他拽着拐杖，屏住呼吸，时刻准备着应付拐杖疯狂的行为。
然而拐杖似乎学乖了，安静了，不动了……？
正当悠悠好奇的时候，突然，他失重往湖底坠去----没有一丝阻力，就像石头在空中坠落一般，“咣当～”一声，坠落湖底！
在跌入湖底的那一刹那，悠悠觉得自己肯定活不了了。可是过了一会儿，他发现虽然从很高的地方摔下来，但是身体并不痛，于是他颤抖地抱着拐杖，慢慢睁开眼睛。
阳光灿烂，蓝色的天空泛着一圈圈的水纹。
四周一片旷野，旷野的尽头环绕着连绵的山脉，绿油油的，生机无限。
悠悠慢慢地坐起身来，看到自己掉到了一块长满青苔的绿色的巨石上，他仔细地检查了一下四肢，让他惊奇的是，他发现自己不仅没有受伤，就连身上的衣服居然都没有湿。
这是哪里？
为什么拐杖不动了？
悠悠看着上一秒还疯狂无比的拐杖，这一秒突然变得安静异常，觉得很奇怪。
“喂，人类小孩儿，你还好吧？”
一个低沉、雄厚的声音从悠悠身边响起。
悠悠吓了一跳，左顾右盼，但却找不到说话的人。
“喂，人类小孩儿，你别找了，我在你的下面。”那个声音又再度响起。
下面？
悠悠往下一看，并没有看到人。
突然，绿色的巨石在晃动，在倾斜，悠悠还没来得及抓稳，像滑滑梯一样朝下滑了下去。“啊~”地一声，一屁股坐到了绿色的草地上。
“人类小孩儿，你还好吗？”这次，那个声音在悠悠身边响起，而且越来越近。
悠悠一回头，正好看到一只怪物正瞪着一对巨大的，像黑洞一样的眼睛在盯着他！绿色的身体，菱形的头！

Luckily， Yoyo knew how to swim…
Yoyo felt really proud that he can swim. He held the walking stick and tried to swim to shore. Yoyo made sure that if the stick went psycho again， he could manage to follow it.
However， the walking stick finally learned to be still. It was sitting in Yoyo’s hand not moving a muscle…?
Just when Yoyo felt safe， suddenly he started sinking to the bottom of the lake， like a rock falling from the sky. Bonk， he then reached the bottom.
Just as he hit the ground， Yoyo thought that he wouldn’t have survived. However， he realized that when he hit the ground， it was the exact same as hitting a bunch of soft marshmallows. Yoyo then slowly opened his eyes------
He found himself in an unusual place. The sky was the colour of pale blue and the blue colour looked like wave of the water covering the sky.
Yoyo sat up straight and realized that he landed on top of a huge rock with moss all over it. Yoyo then started inspecting the place. He then noticed that he fell down in some beautiful grassland. The ground was lush green and it was surrounded by dark green hills. He checked his arms and legs， and found not only he was safe， but also his jacket wasn’t even wet.
“Where is this place?” Thought Yoyo.
“Why is the stick not moving?” Yoyo looked at the walking stick and thought，“a second ago， it was a maniac and the next it was silent.” Yoyo felt very confused.
“Hey human kid， are you okay?”
A loud and low voice echoed through Yoyo’s ear.
Yoyo got a heart attack. He turned around， but he couldn’t find the person that said it.
“Hey human kid， you don’t need to keep looking for me， I am under you.” The voice said again.
“Under me?” Yoyo looked down， however couldn’t see a person in sight.
The rock started to have a rumble and it tilted to one side. Yoyo did not have time to grab on to the rock. He felt that it was like a slide and a steep one.“ARRRRR” screamed Yoyo and he dropped onto some lush green grass.
“Hey human kid， are you okay?” The voice tunnelled through Yoyo’s body and it seemed to be getting closer.
Yoyo turned around， and just caught the glimpse of the voice. It’s head was a diamond shape， and its eye was massive. It seemed like it was looking at Yoyo.
