Hollow Deep Dive System Events and Guide
Upon arriving inside the HDD stage, head downwards and talk to the Bangboo to obtain the Energy-Consuming Jackhammer Bangboo plug-in.
Afterwards, drill your way through the rock tiles by moving next to them continuously to continue progressing.
Talk to the Mine Engineer to unlock the Jackhammer's upgrade shop and charging station.
Return to these three tiles once you have found a Sparkstone, Gear Coins, or if the jackhammer is out of energy.
The jackhammer starts out with 10% energy in store. Fortunately, you can increase its energy capacity through the Shop with enough Gear Coins!
The mine has rocks that become progressively sturdier as you continue heading downwards. Collect Sparkstones and return to the Engineer to upgrade the jackhammer!

 Gear Coins |

 Sparkstone |
Continue mining downwards to collect the three Sparkstones that Appon needs. You can check what's hidden inside a rock tile by checking the icon located on the top-right side of the tile.
Traps that deplete the jackhammer's energy are scattered throughout the mine. Avoid these tiles as much as you can!
Various mine carts are present throughout the mine. Move to the red button tile to activate and ride a mine cart back to the camp to upgrade, or recharge the jackhammer.
While mining, some tiles will reveal arrows pointing to a direction. Follow and mine towards their direction to obtain Gear Coins and Supply Boxes!
The first Observation Data for the stage can be found on the area near the first Sparkstone.
Collect the Sparkstone, return to the camp to upgrade the jackhammer, and then return to break the sturdy rocks to obtain it.
The second Observation Data can also be found near the second Sparkstone of the stage. Upgrade the jackhammer again to collect it.
On the way to the third Sparkstone, a gate blocks the way to a charging station, Gear Coins and a note tile to upgrade the jackhammer's mining range.
Collect the note tile after obtaining the key below the gate to progress downwards even faster!
