Nutsoglobin
Nutsoglobins are a variant of Emoglobin from Mario & Luigi: Bowser's Inside Story. They are only located in the Flab Zone. If the player activates the Nutsoglobin, they are given the option to "spend time with" it. This is optional, but it recommended to do so, because they can give information on how to navigate the Flab Zone, as it is a maze. Unlike other Emoglobins, Nutsoglobins are blue with glasses and likely have hair.
Nutsoglobins will ask Mario and Luigi questions about Bowser. Before taking the quiz, the player can ask Bowser questions through the Nutsoglobin. Each question costs five coins. When the player is done asking questions, they can take the quiz. The Nutsoglobin will then ask the bros. three questions about the information Bowser just gave. Mario and Luigi must answer all the questions correctly, or be forced to fight a Tenderling and redo the quiz. If the Marios answer each question correctly, they will be given 50 coins and the Nutsoglobin will tell the bros. where they need to go next in Bowser's body. Not long after, the player will meet two more Nutsoglobins, the second will ask Mario and Luigi five questions, while the third will ask seven. The coin reward multiplies by 2 every time, and there will be different questions for each Nutsoglobin. They will quiz the player on past information that the player received from Bowser, so it is important to ask Bowser all the questions on the Nutsoglobins' list.
Assuming the player already knows the way through the maze, the Nutsoglobin quizzes are entirely optional.
