Mr. Popo quotes from Dragon Ball

[to Goku] It's a shame that you have such great power yet you make such poor use of it. You need to learn control. Only then will you be able to past this test and meet with Kami.

With this punch, you'll give up!

Oh, got you again. You're not very strong. Please, are you actually the same guy who defeated Piccolo?

I am strong! So you take that back!

You're...weak.

I can't believe it! That hurt even more than Piccolo's punches!

Yes. You beat him and so you assumed you were the toughest in the world. But learn this now: no matter how strong you are, there will always be someone stronger who comes along. To stay on top, you must keep pushing past what you think is strength.

You must be like a stone.

A stone?

Calm and still, so the rain and wind cannot move you. You see?

Oh, that's easy! How's this? [pretends to be a stone]

Stones do not have voices!

Ow! You're making my head bumpy!

Nor do they feel pain.

I did it! I mastered my mind training and defeated the doll!

Not exactly. It was just good timing, the doll's energy ran out.

I was wrong, Popo. We're not the same. He's much stronger than me.

Listen to me, Goku. It is as I told you before dear boy, your speed and skill are matched evenly with the doll. It's just that you haven't finished your mind training.

Mind training...

A warrior's strength is always important in a battle, but it's not enough. The mind is also a powerful weapon and must be developed just like your muscles. If you do not master your mind training, you will never be able to defeat the doll!
