Monstre d'argile
The math word featured in this episode is: volume. Monstrangelo, the greatest sculptor in all of Monstrovia, asks the Math Monster Squad to help him finish his latest masterpiece: a statue of the All-Grumpy Monster. To do this, they must find a container that contains the same volume of monster clay as in another container, regardless of its shape. Phew! Monstrangelo finished just in time. And his statue made the All-Grumpy Monster in a very bad mood.
