So they decided to enter the restricted area of the library. They tried to look for books to make them big again. Suddenly, Argus Filch and his cat Mrs. Norris came. When Hermione and Cerulea saw them, they climbed up onto the shelf. But, they didn't notice that Mrs. Norris was already there. Once she had seen the two of them, she chased them. Luckily, they were small, so they weren't seen.
They were near the door when they decided to just run outside and slip under the door. But they didn't find a book. Hermione suggested that they just go to the Gryffindor common room and ask for help. So they did.When they were there already,they asked help from Percy,Ron's brother.But surprise to Percy they saw Hermione small. But Percy decided to help.So waved his wand and said "Wallus locomotiuslackus klapaucius"and then Hermione and Cerulea got big again they thanked Percy and went out and saw Ron.
"Ron you didn't tell me you have a cousin here at Hogwarts"said Hermione.
"A cousin?Who's that? asked Ron confused.
"Hi! ROnnie"shouted Cerulea.
"Cerulea!? asked Ron
