You grab the doll labeled "Grow up" voodoo. It was a plain looking doll. You didnt know how it could be a voodoo doll. You then notice a tag attached to it.
Grow up doll
Attach a hair from any person to the doll. It can be as much as a lock or as little as a single strand. Say the incarnation "annos progressum transformatio" the person will begin to age faster then usually. You can set it as fast or as slow as you please until they are aged to death or when you say "processus claudum". The person will not turn back unless a Grow down doll is used. Warning once the person has been died there is no going back as you cannot bring someone back from the dead.
You take the doll to the cash register not thinking about buying the grow up doll...at least not yet. You go home and look at the doll wondering who to curse with age.
