The Principal from the Black Lagoon by Mike Thaler, illustrated by Jared Lee is one of the weaker tales in this series.

On the third day of school, our main character is sent to the principal's office... and big surprise, he's heard that the principal, Mrs. Green, is a real monster!

This one had one illustration that wasn't awesome. This is also the very same Mrs Green from the first tale, so we were lacking creativity there.
