In order to hide a bulldog in his no-pets-allowed dorm, scheming fourth-grader Bernie Bridges enrolls his pet as a transfer student.

With the Board of Inspectors threatening to shut down Rotten School, Bernie Bridges only has time for one last money-making scheme, but his friends are too obsessed with a role-playing video game to help him.

Bernie Bridges is the luckiest kid at Rotten School. He wins every game he plays, doesn't get into any trouble, and even finds money! So what's the catch? For the good luck to stick, Bernie has to keep his parrot, Lippy, on his shoulder wherever he goes. Lippy's luck is so powerful that Bernie's friends, Feenman and Crench, want in, too. But the minute they touch Lippy, everything changes-Lippy turns into a bad-luck bird. Now nothing Bernie does goes...

The most popular dude in school? It has to be Bernie Bridges. Just ask him! Bernie wants to win the Most Popular Rotten Student of the Year title. But first he has to prove he's the most popular dude on campus. How? Easy. He'll get Jennifer Ecch, the yearbook photographer, to follow him around. All she has to do is snap pictures of him being popular. When that doesn't work, Bernie decides to throw himself the biggest birthday party ever. But, look...

Jennifer Ecch is so tough... She's at Rotten School on an Arm Wrestling scholarship! Bernie Bridges calls her Nightmare Girl. But she'll do anything to get him to be her boyfriend. That's why she joined the all-boys football team. With Jennifer playing, they can't lose. But wait. If they win, they have to play the National Champion team -- the Bone Breakers! Someone's got to stop the attack of the Ecch -- or else Bernie and his teammates will be in...

Bernie Bridges has it all figured out. April-May June-the hottest girl in the fourth grade-will ask him to the annual girl-invite-boy school dance. They'll dance the night away, and April-May June will totally fall for him. There's only one problem: Reality. April-May June doesn't WANT to go with Bernie. She wouldn't go with Bernie even if he was the last guy on earth. Then Jennifer Ecch-the Nightmare Girl-swoops in and asks Bernie to the dance. Yuck!...

Angel Goodeboy is a perfect angel... You can almost picture a halo over his head! He even wears a T-shirt that says "Mommy's Little Angel. "Bernie Bridges is horrified when Mrs. Heinie makes him share his room with Angel. She wants Angel's goodness to rub off on Bernie. But wait a minute-when no teachers are watching, Angel is no angel! The little sneak takes over Bernie's room. He steals away Bernie's friends. He charms Bernie's girlfriend. Everyone...

The Rotten School kids try to get rid of Mr. Skruloose, an extremely strict teacher.
