Outside of Master Fu's house, Ladybug go next to the door and she de-transform and she walk inside his house and in his room.
Marinette: Master Fu. Trouble with the Sirens, everyone's in a trance and Black Panther and I can't seem to stop them.
Master Fu: Sirens, huh? Guess you'll have to try a stronger power. *He get out the miracle box and open it up.* We already know the rules to this already?
Marinette: Yes. *She look at the miraculouses.* Need something else that will also put you in a trance. Like this! *She pick up the snake miraculous.* See you later, Master. *She leave his house and she stepped out too, she get Tikki out.* Tikki, spots on! *She transform into Ladybug again, she get your yo-yo and revealed the sheep sleigh bell, and Ozzel appeared.*
Ladybug: Hi, Ozzel.
Ozzel: Baaaa! Hello, Ladybug.
Ladybug: I'll need your help. Time to get to Black Panther. *She leap away and she start running across roofs and jump to roof to roof and she spotted Black Panther fighting off the Sirens.*
Black Panther: Don't you ever get tired of singing?
Sphinx: Nope, now quit blocking our music and get into it! *They start singing and Black Panther reach in for a cat nip bomb.*
Black Panther: Taste cat nip, you mythological freaks! *He threw the bomb down and it exploded and Sphinx, Gemini, and Dana start coughing and hacking constantly.*
Ladybug: Catch this! *She threw the black box and Black Panther catch it and he opened it too, he sees Sass.*
Sass: Hello, master Luka.
Black Panther: Hey, Sass. *He put on the Ouroboros bracelet and it's in camouflage mode.*
Sphinx: You think you can beat us, Ladybug and Black Panther? Well think again! *They grab their microphones and start singing until a sonic wave came from their singing and Ladybug and Black Panther evade the sonic wave and land on their feet.*
Ladybug: Tikki, Ozzel, unify! *She merged into Ladysheep.*
Black Panther: Sass, Plagg, unify! *He merged into Black Viper.*
