Something huge sets off Brady's monster detector - a Wishing Un-Well that can walk. It looks like an ordinary wishing well, except that it grants people's wishes with a distinctly ironic malevolent twist, so you end up getting the opposite of what you intended. For example Virgil wishes for a new bicycle. His wish is soon granted as he lands on a new bike, Ember's bike, because he has crashed into her and now both bikes are locked together in a twisted mess… Maxwell wishes for money - which soon drops out of a passing Bank truck, but seconds later Maxwell drives through a fire hydrant, so he immediately loses all of his winnings to pay for the damages. Imagine the chaos once the rest of Ravenville have their turn. Brady and friends put a stop to the evil Un-Well by wishing for it to stop granting people's wishes. This forces it to do the actual opposite, and grant everyone's wishes. Luckily a giant Troll leaves with the well before life in Ravenville gets too far out of control.
