One day
in Hogwartstubbyland it began to rain.
It began to rain
tiny frogs ((Note: the dime is in the picture for scale. It is not raining frogs-on-dimes. Just frogs).
Actually they drifted calmly through the air in eddies and flurries, more like snow than rain. This was to prevent icky splatters. Much more fun could be had, thought the Mysterious Unseen Author of the Frog Plague, if little
living frogs started jumping into everything.
Man, he totally missed his BFF George Weasley. As Lezard watched his handiwork from a concealed alcove, he poured a little of his drink (an unspeakable green ichorous mess he believed to be a sophisticated cocktail) onto the flagstones in honor of his homey.
((feel free to interact w/ one another or with the frogs, or to somehow catch a glimpse of Lezard. Whether or not your char realizes Lezard is to blame for the frogs is up to you, I guess! There definitely are chars who would blame him whether or not they had any proof XD ))
