How to Get Ginny's Things in Harry Potter

Go to the Magical Menagerie just across the street from Mr. Mullpepper's. Break the mini barrels to catch the shopkeeper's attention and run past the black gate where he will catch you. Run to the back of the shelves near the bottom of the screen after he tells you off and turns around.

Flip the switch when the shopkeeper's back is turned or he's away from it. Go through the door the switch unlocked and get Ginny's Scales. Go back out and run to the shelves. Fire "Flipendo" at the switch to distract the shopkeeper. Use this opportunity to run out of the shop.

Turn right and go straight until you find a small shop called Gambol and Japes. Enter the shop and go down the stairs to the left of the Weasley twins. Enter the doorway to your left. The shopkeeper will tell you about the Magical Measurer.

Cast a fully charged Flipendo at the Measurer and a hole will appear to your left. Go through the hole to take the money and Ginny's Quill.

Exit the shop. Go down the alley until you reach an arch and enter the Leaky Cauldron. Smash the barrels to your right, then go straight toward the sickle to fall through a trap door. Flip the switch to go through a door to your right. Go down the passageway.

Cast Flipendo at the three Imps and toss them in the cages. Collect the wizard card that appears near the rolling barrels. Follow the way these barrels are rolling by moving alternately between the gaps. Do this until you can move away and enter the door on the black wall. Your way back will be blocked after entering the door.

Carefully cross the thin plank of wood. Push a large box down to the floor. Go down and push the box to the shorter wall. Climb the box then climb the platform. Go up the stairs to your left until you reach a darkened room.

Cast Lumos in the room to reveal a secret passage. Enter the passage to find Ginny's last item, the Spellotape.
