I can't beat the Goblins in Goblin Camp. I've got my brother out of the cage, but we can't get past the Goblins. What may I have missed in previous levels that I'll need to beat them? I can't find a walkthrough anywhere!!!

You have to catch a certain kind of fairy two times so that you can use them to make Simon run super fast. He will almost fly away from the Goblins. Check the Field Guide to learn about fairies but you have to catch most of them to find out which one has the power to make Simon run fast.
