Skins
The Ash skin is found deep in the Dungeon of Eternal Life. There are golden doors around that block your progress. Sneaky placed lanterns are on either sides of the doors. Light them with Ash, and eventually you will find the new, blue skin.
Venture to the Ancient Tower. If you do not know where that is, find a long stairway in the Enchanted Kingdom that leads up to the throne room. Go left to find a passage leading to the Ancient Tower. There is a squid person there who needs you to round up her children. Equip Major Ruin, Chilla, and Ash to do the tasks. You will find a ramp that Major Ruin can go up. Then, use Chilla. You must repeat this process every level along the way. On every level is a squid child. They will be frozen in a block of ice. Use Ash to melt the ice and the kids will go to their mother. Continue up the ice until you reach the top. The little bug things will make it difficult all the way up, but it is possible if you keep trying. Once you get to the top, you will find the last squid child and be rewarded with three elemental fruits, as well as the new Chilla skin. Get the skin, then work your way to the bottom. When you get there, collect your fruit.
The Flex skin can be found at the Ice place. Venture around until you find the shop that you do not have to walk into. It costs a bit, so you might want to have a full wallet.
The skin for Major Ruin is in the water place shop.
The Pummel Weed skin is in the Enchanted Kingdom shop.
The Rubble skin can be found in the forest place. Again, find the shop and buy it.
Defeating Troll King Thorn
Take out 40 Below and use his Wrecking Ball technique on Thorn the entire time. Do not worry about any of the enemy trolls that Kalus throws around you. Just keep on Thorn with the wrecking ball and go in circles around him so that he and the other monsters cannot get any good shots in at you. When you have Thorn dead, Kalus will appear and try to revive him. As before, do not worry about all the other monsters. Just transform into Chilla and use his Ice Spears to take her out. Note: You may need to do this two or more times if she revives Thorn.
Self-Immolation
When Ash launches a fireball, some flame will linger where you stand. If you morph to a character like Pummel Weed, the flames will alight your character and cause some damage. But you can use Deep Blue with the oil upgrade and shoot napalm.
As Ash, launch a fireball, then quickly morph to Deep Blue and start shooting oil. The oil will be in flames as you shoot it. You will not take damage from the flames because Deep Blue is of the Water element and Fire doesn't affect it.
Immolation Nation (Ash Life)
Once you unlock Ash's flame circle move, you can use it immolate Ash and recover his life.
Unlimited Runes (Money)
When you are heading toward the snow temple, you will find this specific spot. When you have to be Major ruin to shooot across a gap and switch to Chilla, you should fall. Below will be an elemental fruit and three ice "balls". Get out Ash and burn them; you should get coins in most of them. Wait until they all rebuild, then do it again; more coins will come out. This process is long, but it works. When your wallet is full, buy the larger size and come back to get more coins. Do this until you have 999 coins. Then you can go to shops and by out all their elemental fruit and whatever else you want.
