When Chat Noir hears that Marinette is in distress while babysitting Mlle Bustier's new baby, he can't leave her like that. Little he knew that the baby would have a poop. How difficult can it be to change a baby? Ready to laugh at poor Adrien's expenses as he finds out? You're welcome. I suggest not drinking water as you read this. I'm not taking responsibility for you spilling your drink. Honestly.
