OK. I once made the Orb Guide a long time ago but it was deleted so here it is again ^_^.
Glimmer
First Orb-To get the first orb, go pastthe big underground tunnel and to the cave in the following field. Talk to the miner there and he will ask you to help him. Follow the him and take out the weasle things by eatting the rock. Then press the triangle to aim and the O button to shoot. You will be rewarded with an orb.
Second Orb-To get this orb, go to the second field after the cavern and run around until you find a miner standing on a small platform next to a power-up. If he says you can go through it then proceed through the powerup. Then press X and X again so you can fly. FLy around the field and flame each of the crystal lanterns before you wing powerup fails. IF you suceed, you will get an orb. IF the miner says you can't go through the portal, defeat more enemies first.
Third Orb-The third Orb can not be obtained until you have learned how to climb from Moneybags in Autumn Plains. Then you can get this. When you first enter the cavern, go to your right and climb up the little ladder things in the wall. Talk to the miner. If he says you can go through it then proceed through the powerup. Then press X and X again so you can fly. Fly around the cavern and flame each of the crystal lanterns before your wing powerup fails. If you suceed, you will get an orb. If the miner says you can't go through the portal, defeat more enemies first.
