Ghoulia is an enormous fan of the comic book superhero Dead Fast, but can't attend a convention that'll be auctioning the only existing copy of the special Issue #0. After falling into a fantastic Dead Fast-centric dream, she wakes up to find it in her hands! Turns out that Cleo had sent all 10,000 of her royal servants to win it for her. Although Cleo does tell the other ghouls not to spread this info around and ruin her rep.
Ghoulia is actually crying Tears of Joy when she sees the comic book.
It was really adorable when Toralei and the others up and hugged Bloodgood when she offered to let them come to Monster High.
Pretty much the entirety of "Cyrano De Ghoulia" (when it isn't being hilarious, that is): the ghouls agreeing to help shy Ghoulia win over the boy she likes, Frankie taking the fall to distract Moe ("That one's for you, Ghoulia!"), and Ghoulia and Slow Moe walking off hand in hand at the end.
Actually, Slow Moe and Ghoulia in general. Who would have thought two zombie kids could be so adorable together?
Frankie's Basic Diary mentions her first rain shower. Just go on the wiki and read it. It's downright adorable.
At the end of "Fright On", Romulus asked Draculara for a dance. Perhaps he wants to get to know Draculara more to see what his fellow werewolf Clawd sees in her.
Abbey letting Heath take her to the dance, because the fact that he kept trying to ask her and his expression when the other girls try to kick him out shows that he really was serious about her.
Clawdeen apologizing to Draculaura after realizing she was wrong to try to break up her and Clawd's relationship.
In "Friday Night Frights", Clawdeen gets injured during the game. Draculaura has been seeing herself as dead weight on the team throughout the special, and Clawdeen decides to overplay her injury in order to get Draculaura into the field. Clawd catches on and asks, "Are you sure?", his tone indicating that he completely agrees with her plan. She nods at him, and he tells Draculaura she's in:
Draculaura: Are you crazy? We could still win!
Clawd: I know.
Remarkably, it's the facial animation that sells this moment, both in Clawdeen's sincerity after Clawd asks if she's sure, and Draculaura's HUGE grin when Clawd insists on putting her in.
