Bucket- Wonkablack

"No," said Mr. Bucket. "It is much darker. Every surface inside this room is coated with Wonkablack."

"Wonkablack?" asked Keerthi.

"Yes," said Mr. Bucket. "One of my favorite inventions. I was reading the newspaper one morning and they mentioned that someone had invented a material that absorbed 99.965% of light. It was caliginous! It was dimdratty! It was tenebristastic! But still, I thought to myself. Only 99.965? I knew I could do it better, and I had to! So I packed as many chocolate microfibers as I could and mixed it together with a long list of very toxic but no less tasty ingredients, and soon I had done it! Wonkablack absorbs 99.9999999994% of light! You couldn't find a darker dark anywhere outside of a black hole."

"Sure," said Lim. "But how do we leave?"
