The Fight for the Warners

Valentina has a normal life...well..as normal as you can get in the Animaniacs version of Burbank, until the Warner siblings come to her house, begging for a place to stay the night; and change her life forever. She and the warners become closer and closer
until
one day, Wakko's mallet gains the power to hurt, and eventually, kill. Is this a glitch, or is there something more sinister going on?
