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.
