What is a qurckle in Harry Potter?

In the Harry Potter series, a "quackle" is a magical creature that resembles a cross between a duck and a quokka. They are known for their distinctive quacking sound and playful nature. However, they are not prominently featured in the main storyline and exist more in the background of the wizarding world. The term itself may also refer to various minor magical incidents or creatures not deeply explored in the series.
