Zack thought long and hard. What would he do with his unlimited power?
Suddenly an idea hit him. He was curious about what it would be like to be in his sister's current position. With a thought, he made it so.
His room blurred for a moment while it changed around him. His bed was now gone, replaced with a crib much like the one he had put in his sister's room shortly before. Likewise, his dresser became a changing table. Looking down at himself, he saw his clothing, which had been a normal teenage boy's pajamas, had become only a t-shirt and a diaper.
Still, he felt something was not quite right. He gave his wish a little tweak and nearly everything around him turned pink. The clothing changed from babyish boy's clothes to babyish girl's clothes.
He decided to spend time dressed as a baby girl.
