The third "eye" you incinerate, the entire theme of this one is cake. though the voice was pretty much monotone it sounded manic to me, and I envisioned the blue sphere looking a bit disheveled an twitchy, and having insomniac like circles under her eyes.
All the cake sphere talks about is the same cake recipe over and over, although if you listen well you'll find some of the ingredients don't seem to belong in a cake:
"One 18.25 ounce package chocolate cake mix. One can prepared coconut pecan frosting. Three slash four cup vegetable oil. Four large eggs. One cup semi-sweet chocolate chips. Three slash four cups butter or margarine. One and two third cups granulated sugar. Two cups all purpose flour. Don't forget garnishes such as: Fish shaped crackers. Fish shaped candies. Fish shaped solid waste. Fish shaped dirt. Fish shaped ethyl benzene. Pull and peel licorice. Fish shaped volatile organic compounds and sediment shaped sediment. Candy coated peanut butter pieces, shaped like fish. One cup lemon juice. Alpha resins. Unsaturated polyester resins. Fiberglass surface resins. And volatile malted milk impoundments. Nine large egg yolks. Twelve medium geosynthetic membranes. One cup granulated sugar. An entry called 'how to kill someone with your bare hands.' Two cups rhubarb, sliced. Two slash three cups granulated rhubarb. One tablespoon all-purpose rhubarb. One teaspoon grated orange rhubarb. Three tablespoons rhubarb, on fire. One large rhubarb. One cross borehole electro-magnetic imaging rhubarb. Two tablespoons rhubarb juice. Adjustable aluminum head positioner. Slaughter electric needle injector. Cordless electric needle injector. Injector needle driver. Injector needle gun. Cranial caps. And it contains proven preservatives, deep penetration agents, and gas and odor control chemicals. That will deodorize and preserve putrid tissue."
