Zqfmgb

Zqfmgb, according to Madeline Pluto, is a worm that lives in New Guinea. She uses it to presumably win a Scrabble game, as her score afterwards is 957.

Maddison: "'Zqfmgb' Isn't a word! It doesn't even have a vowel!"

Madeline: "It is SO a word! It's a worm found in New Guinea! Everyone knows that!"
