Substitute Teacher

Billy's cousin from the center of the Earth, Nergal Jr., goes to school for the first time, but he is worried that people may not like him. Soon enough, Junior becomes bullied by Sperg, with Miss Butterbean's allowance. Then, Billy suggests Junior to use his shape-shifting powers to take the form of Miss Butterbean, so Junior can help him pass a math test. Junior likes the idea, but he morphs into Miss Butterbean to get revenge on Sperg instead. In the end, Sperg is seen living in the center of the Earth as Junior's pet.

Der Sohn von Nergal und Sis – Nergal Junior – soll die gemütliche Wohnung im Zentrum der Erde verlassen und zu seinem ersten Schultag gehen. Schön daran ist, daß er bei seinem Vetter Billy in der Klasse sein kann – nicht schön hingegen, dass er gehänselt werden könnte. Und genau das passiert auch! Doch Nergal Jr. besitzt die Fähigkeit, sich in andere Personen zu verwandeln.

Nergal Junior va a scuola per la prima volta, ma a causa del suo aspetto e del fatto di essere un novellino ha paura. Viene infatti preso di mira da Sperg, il bullo della classe. Intanto, Billy porta Tenebra a scuola nel tentativo di barare al compito in classe.
