Les Monstres d'honneur

The mathematical word featured in this episode is: same. It's a monstrously romantic day, because Nellie the Angry Monster has to get married! She enlists the Math Monster Squad to help her with the final preparations. First, she needs more stinky flowers to make bigger bouquets. But more flowers make it look like there are more bouquets. A Teletou-monster demonstrates that the number of objects remains the same regardless of the size. And when Goo slid off holding the cushion with the wedding rings, the groom's suddenly formed a line longer than the bride's, making it look like there were more wedding rings for the groom.
