One morning in Fairy Land, Rosy woke up to water her plants. However, there was no water flowing out of the tap. A passing servant says to Rosy to check the dam; when Rosy got there, there was a commotion as apparently, the key to turn on the water from the dam has been stolen by a troll! The only way to make the water flow again was to retrieve the key from the troll, but where can Rosy find him? The villagers told her to ask the all-knowing king of Fairy Land, King Peacock.
King Peacock tells the princess the way to the troll's cave is long and winding, but there is a short cut that she can take, through the dark forest. Not wanting to go through the scary forest, Rosy and her friend Flappy the Butterfly took the long route, despite the King's advice that it will take them a long time to get to the troll's cave with that route. Taking the long road might delay the princess, and the plants in the garden might die if they don't get water soon enough.
After a long and uneventful journey, the duo finds the troll's cave. The troll Carrot, orange-colored and grumpy, tells them that he has they key, but is unwilling to return it unless they get his special dipper from the dwarf who stole it. Flappy asked where can they find the dwarf, and Carrot points them to the direction of the dwarf's tower. A howling tunnel leads the way to the tower, and Flappy and Rosy tried to go flying in to no avail since the wind blowing out was too strong. Flappy decided to sing a song to attract anyone who can help them; soon enough her outstanding voice attracted a villager named Morty, who showed them a secret rock to press to stop the wind from blowing so they can get in.
After getting in, the dwarf named Sneezy refused to give the special dipper back. Rosy tried to reason with the dwarf to return the dipper but failed. Flappy sang a song to change the mood of the dwarf; it worked and he told them that he would gladly return the troll's dipper if they give him another one. So with a wave of her magic wand and the words, "Abracadabra, dipper," Rosy made him a nice new dipper. Sneezy was delighted and gave back Carrot's dipper. Rosy and Flappy returned to Carrot's cave to give his dipper back; he in turn gave back the key. Swiftly, the two made haste to return to the dam with the key, and they made it back in time to Rosy's garden to water the plants before any of them got wilted.
