Initial shipments of Lagoona's second doll include a variant with shoes without fins, which are repaints of Ghoulia's shoes rather than Lagoona's first doll's shoes.

Abbey Bominable, C.A. Cupid, Clawd Wolf, Gillington "Gil" Webber, Spectra Vondergeist, Toralei Stripe Automata (ca. 800 BCE) - Autonomous metal statues created by the Ancient Greek god Hephaistos to perform a variety of tasks. Operetta had a brief crush on Archer, who was a new student a Monster High that many girls found attractive. However, her efforts to entice him mostly sprung from her rivalry with Toralei Stripe as they competed for his attention. The Stich-uation Archer ignores Operetta and Toralei in favor of Nightmare, a demonic horse, and both girls conclude that Archer is not their type. After the disappearance of her father, Robecca came to live permanently with Kinder grubber, who's become an unofficial adoptive mother figure to Robecca and was the one that made her enrol at Monster High. Recently, Hoodude Voodoo has come to live under the same roof as them, but it's unknown how Robecca views him.

As a simulacrum, Robecca does not have family in the same way natural creatures have. However, she and her creator, a Mad Scientist by the name of Hexiciah Steam consider each other father and daughter. Pain Inability: A voodoo doll like Hoodude cannot feel pain and is hardly ever damaged, as Hoodude has been through several deadly situations without a scratch.

Toy Story (1995) Disney teamed up with Pixar to make the first fully CGI movie. It featured self-aware toys. (Pixar has made many other movies featuring A.I.) In Ghoulfriends Just Want to Have Fun, Hexiciah is consistently referred to as Hexicah. This either is an error or a preliminary name.Despite her struggle to take a pacifist route through things, she can get passionate and rather hot-headed when things don't go her way, to the point where steam literally comes of her ears. She usually vessels this passionate trait towards following human's (or monster's) rights. As the feminist she is, she is all about female empowerment and the inclusion of women in the social agenda, which highly influenced her decision to step outside the boundaries and venture into the world of SKRM, where she was extremely outnumbered by male athletes. Her pet, Memphis "Daddy O" Longlegs, is named after Memphis, Tennessee. He sports a pompadour like Elvis Presley. A grandmother has appeared in " Scare-itage", presumably the mother of Skelita's father. She may or may not be the grandmother in the picture in Skelita's diary, who looks more like she'd be her mother's mother. Mechanical robot (1907) - A.I. machines usually cast in stories that bring up the question how much autonomy is required to be considered "human".

Robots go by several terms coming from a history of trying to settle on one, and some of them have grown to mean slightly different things. In all, the terms are "robot", "android" and co, "maschinenmensch", and "automaton".

Extras: Like the other Freaky Fusions, She comes with a Electric Yellow Stand and Brush. She also comes with a unique diary, co-written by Draculaura & Robecca. Fynn is Operetta's oldest and closest childhood friend who taught her how to play and build guitars. Operetta dedicates her diary entries to them, and wishes that Fynn would modernize his communications so they could keep in touch through technology instead. Operetta's ' Campus Stroll' diary Catty Noir became Operetta's friend after she took a hiatus from her popstar career to attend Monster High. Despite Operetta's lesser fan base, Catty Noir was similarly excited to meet her, as Catty's guitar player was a big fan that would often play Operetta's music during her tours. Catty Noir's New Scaremester agenda It is presumed that Operetta befriended Casta Fierce through Catty, who is another famous musician. Casta Fierce's profile In Renaissance Italy, Leonardo da Vinci sketched plans for a humanoid robot around 1495. Da Vinci's notebooks, rediscovered in the 1950s, contained detailed drawings of a mechanical knight now known as Leonardo's robot, able to sit up, wave its arms and move its head and jaw. The design was probably based on anatomical research recorded in his Vitruvian Man. It is not known whether he attempted to build it. During his time at Monster High, he became close friends with Headless Headmistress Bloodgood, and it is implied the two had a romantic relationship.
