"Well," Mike replied. "What would you guys like to do? Since the voice of reason is currently a rock, we're entitled to go a crazy."
The twins exchanged a glance. "Puppies!" they exclaimed in unison.
"You want to be puppies? Both of you?"
"Yeah!"
Mike shrugged and swung the device in their direction. They vanished inside their collapsing clothes in a burst of light. The two piles of clothing twitched, emitting electronic yips, and to the remaining siblings' amusement, two robotic AIBO dogs, one blue and one pink, shuffled slowly from beneath the clothing. They moved sluggishly, bumping into the furniture and occasionally doing backflips, showing not a scrap of the twin's human intelligence.
Mike twirled the transmogrifier about his fingers, turning to his two remaining family members. "Who's next?" he said excitedly.
