One day a Mouse goes to play at a nearby pond. There he meets a Frog. They start playing together and become instant friends.
Frog: We are best friends, aren’t we, Mouse?
Mouse: Of course, we are. Why do you ask?
Frog: Well then, let’s always be together.
Mouse: How can we do that?
Frog: I have an idea. Let’s tie our legs together with a string. Then we can go everywhere together. How about it? Don’t you think it’ll be fun?
Mouse: Wow! That’s an interesting idea. But it might be dangerous.
Frog: How come?
Mouse: Someone might get hurt.
Frog: You worry too much. No one will get hurt. It’ll be fun. Let’s try it.
Mouse: Okay. If you insist.

The Frog and the Mouse tie their legs together. They go everywhere together and do everything together.
Mouse: I’m hungry. Let’s go to the corn field. I want to eat some corn.
Frog: Fine. Let’s go, but don’t run. It’s hard to follow you.
Mouse: Oh, I’m sorry. I didn’t know.

The Frog watches while the Mouse eats.
Mouse: Hey Frog, what shall we do next?
Frog: I don’t know. Let me think. What can we do? Hmm… Ah ha! I’ve got it!
Mouse: What is it?
Frog: Let’s play at my house.
Mouse: Where is your house?
Frog: It’s right over there.
Mouse: I can’t go there.
Frog: Why not?
Mouse: Because it’s underwater. I can’t breathe underwater. I can’t even swim well.
Frog: Oh, I didn’t know. Then I’ll teach you. Just hold on to me. You won’t drown. Besides, your legs are tied to mine.
Mouse: Will it be safe?
Frog: Of course, it’ll be safe.
Mouse: Are you sure?
Frog: Come on. Just follow me.
Mouse: Don’t jump in!!!

The Frog doesn’t listen to the Mouse. He just jumps into the pond. The Mouse drinks a lot of water.
Mouse: I told you not to jump in!
Frog: I’m sorry. I didn’t hear you. Are you okay?
Mouse: Yes, but next time be careful.
Frog: All right. Now let’s swim to my house. Just hold on to me.
Mouse: Hey, this is fun. I like swimming.
Frog: I told you.

The Frog and the Mouse swim for a while.
Mouse：I’m tire now. I want to go out.
Frog: Come on, Mouse. Let’s swim a little more. I’m not tired. I’m having fun.
Mouse: It’s getting late. I don’t want to swim anymore.

The Frog and the Mouse fight. The frog gets mad and does as he pleases.
Frog: I don’t want to be your friend anymore. You can go if you want.
Mouse: But how can I? My legs are tied to yours.
Frog: That’s too bad!

The Frog just jumps into the water again. This time he doesn’t come out for a long time.
Frog: Hey, Mouse, are you okay? There is no answer.
Frog: I guess he’s dead. Too bad. I’ll just keep swimming.

The Frog doesn’t care about the dead Mouse. He just continues to swim underwater. Then a Hawk flies by.
Hawk: Ha, ha, ha. Look down there! There’s a dead Mouse. I must eat it for dinner.

The Hawk comes down fast. It snatches the Mouse and goes up again.
Frog: Hey, what happened! I’m flying!

The Frog looks up and sees the Hawk.
Frog: I’m not a Mouse! Let me go!
Hawk: Oh, I didn’t know you were there. What luck! Now I can eat a Mouse and a Frog for dinner.
Frog: No! No! Please, let me go!

The Frog tries to untie the string but fails. The Hawk eats both of them.
