Let's Go to the Castle is a Season 16 Barney Home Video.
The kids read a story about a Princess who lives in a castle. She gets casts upon a spell putting her in a deep sleep permanently, but then they find out the rest of the book is blank, because the story is incomplete, and it will remain that way until the spell has been working, and the only way to break the spell is to find a rare flower in the forest and bring it to the castle and wake her up. Barney and his friends set off to the castle and go through the forest to find the flower (which they successfully do) and return it to the castle, and fortunately, it wakes her up, and everyone in the castle throws a big party.
