Zouzous Description
Fast as a cheetah! Agile as a panther! Able to hear the smallest noise in places around! Like a cat, he is also afraid of water! But when the adventure calls him, "the fabulous Yoyo leaps to the rescue!" When a mission comes up, Sacha becomes Yoyo! Leader of the group, Yoyo is also the eldest of Les Pyjamasques. Certainly, it only plays two to three months. But when you're seven, a few months, it's not nothing! In his cat pajamas, Yoyo shows incredible speed (he can travel great distances at lightning speed) and agility (he can jump easily from one perch to another in precarious balance). He also has exceptional hearing acuity that allows him to hear the most distant sounds thanks to his "Oreilles de chat!" His powers: Speed! Giant leaps! A super fine hearing!

Sacha
Sacha takes enjoyment on being curious and observing towards things that may interest him during school. He can be easily scared at times; this was especially emphasized in La Légende des Pyjamasques.

Yoyo
He is shown to be the most courageous member of the Pyjamasques. Unlike Catboy, Yoyo he doesn't seem to prefer to have his own way at all, and tends to not act in a superhero's vigilante tone at all. He is also shown to also give out morals and lessons to others who are facing problems, despite him making his own mistakes at other time.

He doesn't even speak in the English language and instead speaks in French.
