Since there were barely any students left at Hogwarts, they could make all the noises they wanted without bothering anyone. Everyone seemed to be having fun except for Percy Weasley, who thought they were being childish.
Y/N joined with Fred and George's shenanigans and helped them secretly place small harmless explosives under random students' beds so that when they returned, a surprise would be waiting for them.
However, Percy confiscated all the firecrackers before that happened, saying they would cause too much trouble for the Gryffindor.
Disappointed, Fred and George left ten of them under Percy's bed instead. Not the dangerous kind, but certainly frighteningly loud. That ought to quench their mischievous desire after seeing Percy's shocked reaction, at least.

Y/N had eaten so much food on the night of Christmas dinner that she could just burst! She had barely finished her fourth helping of Christmas pudding when Hermione had ushered her, Harry, and Ron out of the Great Hall to finalize their plans for the evening.
They discussed for a bit before Harry and Ron reluctantly agreed to impersonate Crabbe and Goyle. Hermione set up a trap for those two blockheads and tricked them into eating chocolate cupcakes with a hint of Sleeping Draught.
After they fell unconscious, Harry and Ron quickly took their clothes and a sample of their hair before heading to Moaning Myrtle's bathroom, where they were met with Hermione and Y/N.
"Did you get it?" Hermione asked breathlessly.
Harry showed her Goyle's hair.
"Good."
The four of them stared into the cauldron. Close up, the Potion looked like thick, dark mud, bubbling sluggishly.
"Yuck," Y/N shivered in disgust. "I can't believe you guys are drinking that."
The three of them gulped, and couldn't believe it either that they were about to consume such a disgusting thing.
"What now?" Ron whispered.
"We separate it into three glasses and add the hairs."
Y/N was initially going to join them in drinking the Potion, but she was going to impersonate Pansy Parkinson. However, that was before she and Draco became friends.
Now, it seemed unnecessary as she could just talk to Draco normally as herself. But of course, that was not the case for the Trio, which is why they had to take the Polyjuice Potion.
Hermione's hand trembled as she added Millicent Bulstrode's hair into her glass of Polyjuice Potion. The Potion hissed loudly like a boiling kettle and frothed madly. A second later, it had turned a sick sort of yellow.
"Urgh— essence of Millicent Bulstrode," said Ron, eyeing it with loathing. "Bet it tastes disgusting."
"Add yours then," said Hermione.
The boys added theirs in, too. Both glasses hissed and frothed.
"Ready?" Hermione looked at Harry and Ron anxiously while holding up her glass.
"Wait, Hermione— " Y/N stopped her, "Are you sure you want to do this?" Knowing that wasn't Bulstrode's hair, she added.
"No, I'm not so sure anymore..." Hermione gulped. "But the plan must go on. It has to be tonight or who knows what Malfoy will do next if we don't stop him."
Hermione took a brave inhale, and before Y/N could have the chance to say anything else, Hermione quickly forced herself to drink the Potion. Seeing her bravely drink the muddy thing, Ron and Harry followed right after her.
