[TOMT] What is the animation called?

Looking for a recent English indie horror animation. One of the main character has a green short bob haircut and has a Russian accent. The setting is a library/study with cute anomalous creatures. One scene has a creature trying to drink a girl's coffee. Another episode is a sleepover where a monitor shows a blinking red dot before a monster attacks, removes a friend's face, and hangs it on its belt she falls down the stairs and the green haired girl tries to stay still not to get caught. I've seen clips on Facebook Reels and RedNote. I need to know the name!
