How to reach Bone Beach from Ossex
The journey begins in the Southern Outskirts south of Ossex. From there, you need to enter the cave system located southeast of the main path and navigate a series of Puff Plant platforming challenges. By using Mina’s Burrow ability to reposition Puff Plants, you can create paths across otherwise unreachable gaps.

The route passes through the Southern Outskirts caves, hidden platform sections, an underground mini-dungeon, and finally Sandfalls to Miner’s Den. Along the way you will encounter invisible platforms, environmental switches, enemy encounters, and several shortcuts that can be unlocked for easier backtracking.
How to clear Sandfalls and unlock the Bone Beach path
Step 1
Reach the main Sandfalls area and locate the central section blocked by a Plasma Vial lock.

Step 2
Find and transport bombs to TNT-filled mine carts scattered around the region. The bombs have very short fuses, so timing is crucial.

Step 3
Detonate each TNT cart to permanently remove the obstacles blocking progress.

Step 4
Navigate the shifting sands, moving platforms, spike hazards, and enemy-filled passages while opening additional routes.

Step 5
Destroy all required mine-cart barriers to reveal access to the central locked area.

Step 6
Spend 3 Plasma Vials at the gate and enter the newly opened section.

Step 7
Defeat the Major Miner mini-boss, who uses pickaxe shockwaves, spinning attacks, falling rocks, and summoned miners during the encounter.

Step 8
After the battle, continue forward to finally arrive at Bone Beach.
