The Magic Beans and Where to Put Them

Magic Beans can be planted by young Link in soft soil. Soft soil looks like a square of light dirt with a hole in the middle. When a bean is planted by Young Link, it will transform into a magic moving platform for adult Link. These magic moving leaf platforms are very useful. Magic Beans can be bought from a character near the entrance to Zora's River. It costs 10 rupees for the first bean and the price goes up 10 every bean you buy. Also, every soft soil spot except the one next to the Magic Bean merchant has a gold skulltula in it. Drop a bottle of bugs on the soft soil to get it. It doesn't matter whether or not you've already planted a bean there.

There are 10 spots to plant beans, and as such you can only buy 10 beans.
