I shrunk my stepbrother

Description: My younger stepbrother really pissed me off. he constantly makes stupid pranks on me and gets in the way of my life, i practically hate him! i need to teach him a lesson so that he starts respecting his older stepsis. how lucky that i got my hands on a magic drink from a miracle shop, the one who drinks it will become the size of a bread crumb... of course i'm going to take advantage of this and make him do something particularly nasty!
