First Years won’t get much sleep on their first night there as it’s spent hypothesizing, meeting their room-mates, looking out windows and marveling at their Common Room. Many don’t even fall asleep in their own dorms or beds. Some fall asleep on the couches, on the window seats, large pillows that have been arranged on the floor, etc.
It’s the Prefects who shake them awake after suppressing a chuckle at the scene: ink stains on cheeks, some piles of candy (gathered together as neatly as possible) and an overall messier Common Room than usual. They rise a little earlier to tidy up together, while still chatting about the night before and their expectations of the day ahead.
Unlike the other houses, the initial question asked by first years regarding the giant squid isn’t “Is it friendly / Are there more?” (Hufflepuff) or “Has it ever eaten anyone?” (Gryffindor and Slytherin). It’s usually “But what does it eat?” Squids are known for being very aggressive hunters and, at first glance, there doesn’t appear to be any life large enough that would sustain the squid for any length of time. Many generations of Ravenclaw have attempted to answer this question, with mixed results. At present, it appears that it will consistently eat toast, fried fish, raw fish, deer carcasses, rock cakes, and Licorice Wands. Slytherin students have found out about the ongoing mystery and continually taunt the Ravenclaws about it, saying that they see the squid every day from their window, know exactly what it eats, and can even talk to it. Their claims remain unconfirmed.
