The Mammoth Academy in Trouble!

Oscar, Arabella, and their friends can't wait to begin their second termat theMammoth Academy. But when they arrive at school on the first day after winter break, there's a threatening graffiti message waiting for them.

It seems the Cave Skool has moved nearby, and its pupils—those wild and dangerous animals called humans—are wreaking havoc. When a huge snowstorm hits and everyone is trapped inside the academy, the humans attack!

With a little teamwork and a lot of explosive materials, the mammoths and their friends just might be able to save the day.
