Skylanders: Giants/Junkyard Isles

You have been introduced to Flynn's "new" ship, the Dread-Yacht. But before tracking down the hermit, some replacement parts are required.

The dread-yacht (somewhat violently) docks onto the side of the island, sending a mabu flying.

Dread-Yacht
Before heading onto the island, you can visit Persephone's Cabin (near Cali) to start purchasing upgrades, though they haven't been formally introduced yet. If you do not wish to purchase upgrades yet, continue onto the island.

Rotten Moorings
There is a root runner and some bone chompies here. (Note: If you did not access the Life Gate in the previous chapter, you will be formally introduced to the root runner at this point.) Either take them out using your attacks, or use a bomb (walk into it to pick it up and press to throw in the direction you are facing). The walls here can be destroyed using a bomb or a Giant's attack.

Walled Ruins
There are two more root runners here. Finish them off, then destroy the next wall. Destroy the pile of bricks on the left as well. Go to the left and drop down.

Rotten Bottom
There is a cave entrance here.

The Cave
Inside is some debris, as well as a tzo crystal. These can only be destroyed by bombs, but can also be destroyed with the attacks of Whirlwind, Flashwing, Crusher and Prism Break, and leave valuable loot. There is also a breakable wall. You could grab the bomb from earlier and quickly drop down, enter the cave and use it, but using a Giant is probably easier. The 1st Treasure Chest is revealed. Bust it open, then exit the area.

Rotten Bottom (cont.)
Use the bounce pad to get back up onto the mainland.

Walled Ruins (cont.)
Smash any other debris and walls blocking the path, then go through.

Crumbling Remains (Undead)
There are a few chompies to kill. As always, you can use a Giant to destroy these walls, but to get the bomb, push all the blocks to the right. Then push the furthest block into the gap to form a bridge to a platform with some treasure and the bomb. You can destroy the next two walls from this position, allowing you to pass through.

These guys aren't too difficult to kill, just avoid their spear attacks. A bounce pad will reveal itself on the right. But remove the boulder on the left first.

Hephaestus' Chain (Undead)
There is a chain-pull Feat Of Strength here. Using a Giant, press to grab onto the chain, then mash  to pull on the chain. Eventually, an island will be pulled in. The 2nd Treasure Chest is here. Go back on the mainland.

Crumbling Remains (Undead) (cont.)
Use the bounce pad to get onto the platform and collect the Octophonic Music Player.

Dread-Yacht (cont.)
He turns on the music player, which blasts a funky tune.

The ship departs the island.

The ship docks onto the next island.
