The members of the trio include:
Les Mascrapules show envy and jealousy towards Les Pyjamasques on what they have. As seen in their recent appearances, they tend to be attached to Les Pyjamasques' certain items such as their crystal.
In similarity to Luna Girl and the PJ Villains motives, Les Mascrapules are motivated by ther desire to have the things they want by any means necessary. Their appearances involve them stealing objects in which Les Pyjamasques own out of envy.
