The Class from the Black Lagoon

It's another scary day at the Black Lagoon . . . for the new teacher, Mrs. Green. There's a new class coming for the first day of school and Mrs. Green is worried. Is it true that the class is really weird and that they put their last three teachers into early retirement? Will the students really turn into horrible ghouls as soon as they get to school? Will Mrs. Green really need her ultimate survival kit to teach the class or tame the class?
