Below is a walkthrough for the A Golden Feast Chapter 3 quest in Eastward.
Meet William and Daniel at The “Big” Station
Make your way to the subway and take the train to The “Big” Station to trigger a dialog event.
Head for Quake Valley
Head north of The “Big” Station then go east for the next two areas. You should come to a cave in the eastern part of the City Outskirts. Enter the cave and work your way through it. When you come to a fork, take the left path through the scattered pots (and enemies) to find a chest with a gear part. Then follow the way forward east. After moving through a couple of areas, you’ll find yourself in Quake Valley where a dialog event will trigger.
Find the Temblor Fish
Follow the northern path deeper into Quake Valley. When you reach the flooded area with sunken cars, taketh the right path (watch out for the bees in the barrels blocking the car bridge). When you reached the cracked stone pillars, drop a bomb to destroy them, then head to the stone dock. Switch to Sam and use her ability to remove the flowers in the lake. This will cause the raft on the other side of them to move south with the flow of the river. Follow the raft to the southwestern part of the area clearing the flowers from its path as you go. It will eventually stop near some cars creating a bridge for you to cross leading to the next area.
Follow the path around the pond then drop a bomb near the cracked stone pillars at the end to destroy them. Watch out for the frog enemy in this room who will spew out poison all over the place. In the next area, there will be venus flytraps scatters all around the ground. If you hug the left side of the area, you’ll pass some cracked stone pillars and end up at a chest containing a gear part. Return to the stone pillars and use a bomb to remove them then keep heading forward until you reach an area with a raft that that is moving in a circle in the water. Hop on the raft and use Sam to clear the flowers, you’ll need to do this two times. After the second set of flowers have been dealt with, switch to John and hit a bomb next to some stone pillars to destroy them. You can then get off of the raft on the dock across from where you started and move the giant crate out of your way to proceed deeper into Quake Valley.
Pass through the next area reaching the following area then loot the chest there for 3 Daikon. Head through the southern exit in this area to reach another area containing a chest with a Heart Orb. Return to the previous area and follow the path east until you reach a room with a fallen log on the left side and a raft on the right. You’ll need to split up Sam and John, take Sam through the fallen log. Use her to free the raft then switch to John and use it to reach the other side. You’ll then need to use Sam to clear the path forward for John ultimately getting him to the northern part of the map where he’ll be able to lob a bomb over to Sam’s side destroying some stone pillars blocking her way forward.
In the next couple of areas, keep switching between Sam and John to clear the obstacles in their path. Watch out for the crows, they will attack whoever is your active character which can be a pain when you are controlling Sam. When you reach the waterfall section with John, drop a bomb by the cracked wall behind it to find a hidden room with a chest containing a Pearl of the Valley. When you enter the room with a jeep in the middle of it a dialog event will trigger. When it ends, you’ll start a driving mini-game and the jeep even has nitro! When you reach the end of the river a dialog event triggers.
Make sure you save and stock up on healing items. When you’re ready, head south to face the mighty Temblor Fish! This monster likes to move through the ground tremor style and throw tractors at you. Use your bombs to blow up the tractor while avoiding the beast. When it comes out of the ground, deal as much damage as you can to it. It will also slam into the side of the room causing giant rocks to fall dealing damage if they land on you. The fish also will spawn additional tractors into the fight to throw at you. It will guard them by moving your bombs away from the tractors. You can drop a bomb under where a tractor is going to land to destroy it instantly or try to kite the fish away to give the bombs time to go off. Once you take the beast down, a dialog event will trigger and you’ll receive a Golden Valley Snapper!
Return to Rocket Mansion
Head back to New Dam City via the train and speak with Assistant Yasu (the guy in black suit and glasses) on Princess Avenue. If you found the Pearl of the Valley, you can give it to him for 200 salt. Continue to Rocket Mansion and enter Alva’s house for a dialog event.
