the cubule animuse is a nest of souls
It means 'Nest Of Souls' off of Babysittier's a Vampire.
The plot is that a boy is proven irresponsible when put in charge of his little sister. The parents hire a babysitter, Erica, who ditches and while that happens, her friend, Sarah gets in a fight with her boyfriend, Jesse, and literally gets thrown all the way to the Morgans'. She lies and says she is filling in for her friend. In the middle of the time that Sarah is babysitting, she leaves. A boy, Ethan, goes to pick up her phone and images of her flash through his mind. She leaves and Ethan tells the other boy next to him, Benny, that they will follow her. Benny thinks it is a Dusk prank because of the new movie being released. That is, until Benny uses night vision goggles and says that she IS A VAMPIRE. They run back to their house to see that the Grandma had fallen asleep and that the little sister was bored. The pizza guy arrives and unknowingly, they invite him into the house. It turns out that the pizza guy was one of the minions of Jesse and was a vampire too. Sarah returns and helps defeat him. The boys get a video call from their best friend, Rory, about a party hosted by the drama club (who are Jesse and his gang). The boys find it necessary to save him so they go to the party. While at the party, Erica gets bitten by her boyfriend (deja vu) and bites Rory. Benny and Ethan and Sarah get out, leaving Rory and Erica behind (totally opposite of the plan guys.) When they get back to Ethan's place, Grandma Weir, Benny's grandma, is putting Jane to bed. The next night was the night of the Dusk premier where Jesse and his flock were going to use a box that can trade a soul for a dead soul called the cubule animus (Latin for nest of souls) to bring back his past vampire army. The grandma says that Ethan is a seer and that Benny was a spell master and that she was an earth priestess. At the premiere the boys are able to stop the attack and get Jesse away to destroy him personally. Ethan kills him by opening the cubule animus, releasing the absorbed Dusker fan souls which "eats him alive" and trapping him in the box. They bury the box and are done with it. Or so they think.
