And they found castles and treasures and jewels and gold

But none of these made them really happy
And their bright colours did not come back

When the Teddies found some animals and birds they did feel a little bit happy, and they quickly looked at their wings to see if their colours had come back, but they hadn't  at all, so they knew they still had not found the most precious, special  and beautiful treasure in all the Universe

And the Teddies flew on searching and searching for a very long time without finding the treasure
At last they decided to fly back to the Rainbow and tell the Rainbow Fairy that they could not find the treasure
That would bring back their bright colours and make them happy again

They began to fly away from earth
