Sprout was toying with one of the bubotubers when she was confronted with two questions from two students. "Mr. Greenly." she said looking at the slug-like creature wiggle in Otis' pot, "I must have mistaken myself, that creature in your pot is in fact a flobber worm." She took the flobber worm out of the boy's pot and put it in her desk. Then, she replaced the disgusting flobberworm with an even uglier bubotuber. "Mrs. Woddedorf." She said as she turned her head toward the young Gryffindor, "I pretty much want you to write an essay on what you know about the bubotuber."
