Cannon, second year, and 2nd floor girl's bathroom

Murtle Warren was floating around her bathroom on the second floor one day when suddenly, a "PING!" sound was heard and an old Arabian-style lamp fell on top of her head and after a "CONK!" it continued into the stalls below. Shocked that something actually hit her for the first time in fifty years, she ignored the first pain she had felt in so long and floated down into the stalls to investigate the item that fell from above her.

Reaching it, Murtle reached out her hand to try and turn it over so she could get a better look. Once she did, her thoughts were trying to piece together what it could be as the only reference that popped into her head was that of a children's story from before her three years in Hogwarts all those years ago.

Astonished that she could properly touch it without resorting to using her poltergeist abilities, Murtle picked up the thing she thought might be a dish of some kind and then proceeded to brush off some of the water that was always around in her bathroom.

Suddenly, a pink mist enveloped her body starting to integrate her essence as she was drawn closer to the tip in the front of the lamp. 'Lamp! That's what it's called!' she thought as she was changed while being pulled into the old lamp. New knowledge and skills she never thought to learn before were being imprinted onto herself as she took a look around her new living space.

The next thing she was aware of, was the sound of someone opening the door to her bathroom.
