This is LittleBlue.

Here is he at home, with his dad and mum.

LittleBlue has many friends...

...but his best friend is LittleYellow.

LittleYellow lives with his parents in a house just in front of LittleBlue's one.

LittleBlue and LittleYellow play always together, and also with others little colors.

One day LittleBlue's mum told him: "I have to go out. Wait me at home".

But he wanted play with LittleYellow and he went out to looking for him.

Where were LittleYellow? 

LittleBlue looked for him everywhere!

Here is he!

LittleBlue hugged LittleYellow.

And they hugged so strong...

..that they became green!

When they went back home, Blue Dad and Mum told them: "You are not LittleBlue. You are green!"

And Yellow Dad and Mum told them: "You are not LittleYellow. You are green!"

LittleBlue and LittleYellow were very sad and they started to cry. Their tears were blue and yellow.
