Head west to the dead end for an Opal and then backtrack and climb up the vines. Continue south until the path opens up into a small room and check the north wall for a hole that leads to 4200 Gald . Before leaving the room make sure to check the rocks on the east side to grab Scratchy and then you can continue south.
The Lake Area has no treasure to gather, so head straight through and zone to the Central Region.
Head south to the vines and hug the south wall to find a hole with 3700 Gald . Hop back down to continue south and at the T section hug the west wall to another hole with a Striped Ribbon . If you continue south you’ll reach the exit, but before continuing to the South Region head north to a dead end to find a Mysterious Bead .
In the South Region head into the small room and check the northwest corner for a hole containing a Guardian Emblem and then continue south the the T section that leads west or east. Start by heading west to the dead end for 8000 Gald and then hug the south wall as you head east for a hole containing the Bonfire extractor. You can now leave to the south to enter Sillea Tundra.
