Hello,
I brought your idea up to the team and unfortunately, we will be declining this suggestion at this time. After much consideration, the team came to the conclusion that the broom model will most likely be difficult to create due to its size. Another thing, we believe the “yip yip” sound which was mentioned may become annoying or repetitive, along with the fact that no other brooms have sound effects when used. Although, please do not hesitate to suggest more items as we may be looking into further none-HP items in the future!
Once again, thank you so much for making a suggestion though! We greatly appreciate you for taking the time to write this thread!
