Riddle School / Love Me Tenor At Royal Woods Middle School, Lincoln tells the viewers about Spaghetti Day as everyone is in line for it. He, Clyde, Liam, Rusty, Zach, and Stella have signed up for a class called EAT. When Lincoln and his friends finally get their spaghetti, they end up finding out that the spaghetti that everyone was given was spiked with hot sauce. Lincoln's group finds a letter for the Action News Team from the Swindler where they must solve the Swindler's puzzles that tie to different pranks. Once they get through more clues, they must put the letters together and find the Swindler before the "big one" is unleashed. As Lincoln, Clyde, Liam, Rusty, Zach, and Stella are walking home from Gus' Games & Grub, they double back when Liam missplaces his retrainer. Upon arrival, they discover that Gus is good at singing opera. While he dreamed of singing on stage, Gus is too shy to sing on other people and only cuts loose when he's alone. This gives Lincoln an idea to help get over his shyness. They start by having Gus sing in front of an audience of plush toys. Then Gus tries his performance at Jean Juan's French Mex Buffet's open mic night hosted by Tyler which he gets help from Lincoln and Stella. With Liam's retainer still missing, Lincoln and his friend find that Gus has turned Gus' Games & Grub into Augusto's Opera & Antipasto which they have a hard time getting used to.
