"Fire potions. I think." Bowser continues his work even as he explains it. He mixes some lava from a bucket into some berry paste in a bowl. Then, he strikes together his new silver-colored bands to produce sparks which set the concoction of fire. "These berries are connected to fire and heat somehow."

"I'm betting it'll let me use my fire somehow." It won't actually work as things are, but Bowser hopes that it will.
