"Catty? wha-?”
“try these on, Ellie! I will make you into a fashionista yet~”

Finally, some cousin stuff
Catty and Eloise are very much cousins, Catty's dad and Eloise's parent are siblings
Eloise has a dad and a parent, his parent took their husband's last name, thus his last name is Sunbeam and not Noir, like Catty's is
Eloise is literally made to be the sun to Catty's moon, thus why he's orange verses Catty's black, and his hair is bright yellow blond, etc. etc. is sun aesthetic

Eloise literally starts going to Monster High because Catty chats it up to him after she starts going

And now you all see the reason to why Eloise has such huge floofy hair, runs in the family

Anyway! cousins! cousin stuff
Honestly just mention Heath, Catty, and you'll get him into whatever you want

Catty-Monster High
Eloise-Me
