School of Magical Beasts. The Race with the Crocodile

In the Winterstein school, there is a secret — magical beasts that talk to the students and help them. A penguin, a turtle, a bat, a chameleon, a piglet, a cat, and a fox are always by their owners' side.... But many in the class still don't have magical beasts and everyone is eagerly waiting for their turn.
The teacher catches one of the students, Silas, in a nasty act: the boy is threatened with expulsion. But instead, he gets a magical pet, a cheeky crocodile named Rick. And now these two are causing mischief together!
At the summer camp, Silas and Rick will sneak into the archaeology museum and cause such trouble that their classmates will have to save them. The guys and their magical beasts are in for a dangerous adventure. They urgently need to figure out how to sneak into the museum at night, rescue Silas and Rick, and restore the exhibits before the scientists arrive.
Will they be able to pull it off and keep the secret of their magical beasts? And who will end up with the talking koala in the end?
