The Smurfs were preparing for the castle's birthday party in the middle of the forest.
Some Smurfs entered the room of the two dwarves, singing:
"Today is the castle's birthday, wake up!
The forest is decorated, we'll have fun and dance!
We'll go to the castle and fill our treasure chest!
Come on, wake up, wake up!"
Sile the dwarf and his sister woke up startled and hid under the covers, listening to the dwarves singing:
"We're late, friends!
It's the dwarves' birthday!
Today we'll dance and sing!
We've defeated the worm!
The castle is calling, dwarves, come!
Come on, draw back the curtain, dwarves!"
The leader of the dwarves, Poncy, entered and said to them: "Happy birthday, friends! Come on, let's go to the square. We'll meet here."
