This door is where…

This is a secret doorway for the Monsters.

Next to it is a doorway made for Fairies.

They open their doors and make their way to the library where they go to storytime. 

Then they come back and they fly around to the ceiling and in the kitchen. Then they have porridge pancakes for breakfast.

Only Fairies, Monsters, Mummy and Daddy can open the door. And Gavin.​
