Once upon a time, in a far away kingdom there lived prince Marco, prince Paul and princess Mary. They are friends and like playing in the forest.

Little did they know that different mystical creatures like dragons and wizards are living deep inside the forest. 

One day while playing, they forgot about the time and got lost deep inside the forest. Suddenly, a disturbed hungry dragon took the princes and flew away.

Not knowing what to do, both princes shout for help.

HELP! HELP!

HELP! Somebody! Anybody! Please!

Suddenly, an old wizard that heard them appeared.  They asked him for help because they want to save the princess. 

What seems to be your problem princes?

Please help us save our friend. She was taken by a red dragon.

The wizard pointed to them the path going to the cave where the dragons live. He also gave them weapons for their protection in their journey.  

Before leaving, the wizard warned them that the red dragon is a very intelligent dragon, and it will try to outsmart and trick them.

Remember this very carefully. When the dragon ask you questions, the answers will only be found inside the cave, because those are the only things it can see.

Upon reaching the cave of the dragons, they saw a dragon guarding the entrance. It breathe fire to them. But with the help of the shield that becomes bigger, they were able to deflect the fire.

When the dragon stops breathing fire, princes Marco and Paul were able to throw the trident that hit the dragon's heart. The dragon died.

Upon reaching inside the cave, they saw the princess tied up in a huge stone. They slowly approach the princess but the red dragon suddenly appeared in front of them. 

How dare the both of you to kill one of my kind! 

We are just protecting ourselves and we need to save our friend!

The intelligent dragon then made an agreement that they cannot refuse. 

I will let go of the princess only if you answers all my three riddles. If not, all of you will stay here forever and become my slaves.

Both the princes remembered what the wizard told them about the intelligent dragon.  But they don't have any choice.
