You had to be careful when eating anything from Fred and George Weasley. The Canary Creams, for example, looked and tasted like ordinary custard cream cookies, but eating one would turn you into a giant canary. However, within a minute, you’d molt your feathers and turn back into a person.
I purchased this adorable Canary Cream from LunaTiqueLife on Etsy. I’ve also purchased the Boxing Telescope and the Mayhem This Way sign.
