Volcano - Hinox Mine

Hinox Mine - Stage 1

Grab all the items then use the boomerang to retrieve a bomb from the pillars to the side. Use these bombs to destroy the block and shoot the switch with the bow. Cross the new bridge, stack two boomerang heroes, then have the archer trigger the two bombs in front. Next, quickly grab the two other people to form a full totem and quickly hit the last orb to activate the triforce gateway.

Hinox Mine - Stage 2

Have all three guys board the mine cart to get moving. Take a single boomerang hero and retrieve a bomb to be thrown at the big cracked block. This will expose a switch. Stack three heroes with the archer on top and shoot the orb to switch the tracks so you can reach the triforce gateway.

Hinox Mine - Stage 3

Get all three of your characters onto the cart to get moving. Now the goal is to activate the three switches in the middle of the room by setting off the line of bombs next to them. Start by flipping the blue switch off to the side with your boomerang to switch the tracks. From here you should be able to activate two of the switches by retrieving bombs with your boomerang then throwing them into the circular pillars. Once both orbs are activated, switch the tracks again and shoot arrows at the bombs by the final orb. This will open the gate that leads to the gateway. That is your next stop.

Hinox Mine - Stage 4

This boss encounter can get pretty rough if you're in single player mode. Get everyone on the cart to get started. The Hinox will show and start throwing bombs into your cart. Picking up the explosives and then tossing them back is your best option. The boomerang can stun him too if you hit him with it. You'll want to spread out your crew around the cart, as the Hinox tends to target the human character. So once the bombs pile and you can't keep up, simply switch to the character who is farthest away from the danger zone to avoid damage. Arrows can damage the Hinox as well if you get the opportunity to score a hit. Once you do enough damage, another Hinox will appear. Just patiently stick with the same tactic until you finally succeed and defeat the boss.
