Tikki and Plagg emerge from the phonograph to see Master Fu being chased by ghosts and Alya using a pillow to defend herself against Nino. Nino:Alya, for your birthday, I'm going to buy you flowers. Hortensias, roses and Lilas! Alya screams. Plagg:I better go find my owner. I just hope he's not living a nightmare without me around. Plagg flies through the window. Tikki:Alya, it didn't work! Wayzz:I'm sorry, Master, we should've warned you. Master Fu:we'll talk about it later, Wayzz! Alya:right now, we have to end this nightmare! Alya:Tikki, spots on! Alya transforms into Ladybug. Meanwhile with Plagg, he is flying back to Nathanael's house. Sandboy is watching from above and smirks when he sees Plagg. Sandboy:Kwami in sight. Ladymoth:that's Chat Noir's kwami. Capture it or follow it all the way to its owner. Sandboy chases Plagg. Sandboy:the Sandboy just checked in. Now nightmares can begin! He shoots sand out of his pillow. Plagg:I already know what my nightmare is and you'll never get me to eat dairy-free cheese. Sandboy groans, Plagg goes into an underground metro-tunnel and Sandboy narrowly avoids getting hit by a metro. Plagg:hahaha. I'm your worst nightmare. Plagg goes through the wall. Ladymoth:argh! You failed. Ladybug and Chat Noir will be here soon! You must get me their Miraculouses! Ladymoth doesn't see dust falling around her. She hears something behind her and turns around to see someone lying on the floor. ???:Marinette......... Ladymoth:m-mom? ???:it's your fault that I'm dead! Ladymoth starts crying. Ladymoth:n-no! I-it's not my f-fault! Meanwhile with Ladybug, she's on a rooftop watching the chaos below. ???:what's going on? She turns around to see Chat Noir. Ladybug:someone has been akumatized tonight. Look! His cloud is shaped like a pillow! I'll bet you anything that's where his akuma is. Chat Noir:awesome! Then it's time for a pillow fight! Both Ladybug and Chat Noir attack Sandboy, Sandboy dodges both attacks.
Sandboy:you won't be able to fight your worst nightmare for long. He shoots sand from his pillow, the sand explodes once it comes in contact with something solid.
