The four villain kids are sitting in the Remedial Goodness classroom, wondering where the teacher had gotten too, when a green and brown blur drops out of the rafters, slides down a drape, flips into the air, and lands on the teacher's desk. Once the blur is no longer moving, it turns out to be a very sharply dressed mouse wielding a megaphone. "Hello, class!" he announces in an amplified squeak. "My name is Basil. Welcome to Remedial Goodness! Your original teacher is unavailable, but I assure you that you will learn a great deal from me whether you want to or not."
"Now, roll call! I have "Gaston son of Gaston" and "Gaston daughter of Gaston" on here, that's rather unfortunate, do you perhaps have nicknames?"
