After obtaining this accessory, continue forward. There's a gear you can step on ahead, but let's head right first to grab an item.
After getting the item, turn back and climb up using this wooden plank.
Climb the stairs and prepare to walk along the pipes. Let's go left first.
At the end, you'll get an item. Also, use your bow to shoot down the bag on the left.
Next, turn back and head to the other side of the pipe. When you see the red thread halfway, be careful—there's another bag above that you can shoot down with your bow.
Ignore it for now and continue following the pipe. Ahead, you can jump down to cross to the other side via the pipe.
Once across, you'll encounter three self-destructing fat enemies. Defeat them all. There's a chest on the left, and behind it is the material we shot down earlier with the arrow bag. There's also another material on the right.
There are stairs next to the fat enemy on the right that lead up. Let's keep climbing.
After crossing over with the rope, ignore the ladder on the right and head left to collect the bag material we shot down earlier with the bow.
Continue forward to find another material. There's also a path to the right.
After collecting this material, crawl inside.
Walk to the end inside, crawl out, defeat the enemies opposite, and open the chest.
Open the chest to obtain the healing item "Container Maintenance Fluid".
