I play the biggest role in the books. In Harry Potter and the Sorcerer's Stone, I used my flute to get past Fluffy. Fluffy is a three-headed dog who only falls asleep when music is played. After I got past Fluffy, I almost got choked by Devil Snare, a plant that wraps itself around its victims and then chokes them. Fortunately Hermione used bluebell flames to save me. THANK GOODNESS! I got attacked by winged keys but THANKFULLY I lived. With Ron's help, I checkmated the king on a larger than life chess board. When I got to seven bottles of potions, I drunk the right bottle with Hermione's help. Finally I killed Quirrell with my hands and saved the stone.
In Harry Potter and the Chamber of Secrets, I got into the chamber by jumping down a big hole. Then I found Ginny Weasley, Ron's sister. Tom Riddle set a big basilisk on me which I defeated with the help of both Fawkes, the phoenix, and the sorting hat. I was bitten by the basilisk, but Fawkes saved me. I always knew he loved me. I am the one who saved Ginny from Tom Marvolo Riddle in the chamber.
In Harry Potter and the Prisoner of Azkaban, Ron's rat, Scabbers, escaped. We chased him until a giant dog broke Ron's leg. I went through a trapdoor into the ground after Ron. I learned that Sirius is my godfather. When everyone came out of the trapdoor, Lupin changed into a werewolf. I was saved by Snape and woke up in the hospital wing. I saved both Buckbeak and Sirius with a timeturner.
I got all the action in Harry Potter and the Goblet of Fire. I was able to get past a dragon with my trusty Firebolt. I escaped grindylows in the lake and rescued Ron from the merpeople. I then got through a maze, faced Voldemort yet again and survived.
