Grow a bean stalk to the Giant's Cloudland.
+9 for guess Gnome's name and getting beans, +2 for planting beans, +2 for reaching top of beanstalk, -4 for eating beans.
First you will have to get onto the Gnome Island. Then, you have to guess the Gnome's name in three tries. His name is "Nikstlitselpmur", which is Rumplestiltskin spell backward. The magic beans are your reward for guess his name.
Don't eat the beans! If you do, you will not be able to complete the game. Be sure to save the game before trying to climbing the beanstalk as it is very easy to fall off (to your doom unfortunately).
The Magic Beans are your reward for guess the Gnome's name. His name (which I can't imaging the pronunciation), is Rumplestiltskin spelled backward. You get this idea from the note found in the Witch's house. After you have the beans, you can plant them. The clover path is a good place for this. Planting the beans will cause them to grow into a massive beanstalk. Climbing this beanstalk will take you to the Giant's Cloudland.
