Mr. Rzykruski is the new science teacher at New Holland Elementary School. He has a thick, Eastern European accent and a unique way of explaining things. He connects with his students, but parents misunderstand his passionate teaching style. Mr. Rzykruski serves as a mentor and inspiration to Victor, teaching him that science can do both good and bad things and that if a scientist does not put his heart into his experiment, there could be disastrous consequences.
Mr. Rzykruski bears a strong physical resemblance to acclaimed horror icon Vincent Price (a favorite actor of Tim Burton's).
