More Trees Than Beanstalks

A boy who lives in a dull town and wants some adventure finally gets it one day.
His grandfather dies, leaving him only one possession: a bag of supposedly magic seeds.
The boy was excited, and immediately planted the seeds, but they didn't grow.
He waited for a month, and one day, he woke up in the dark. Instead of the field around his house, there was a forest.
Craving adventure, he enters the woods.
