No sooner had Rob left the Male toilets, the next change began:
Rob's skin turned bright blue, like the picture of his monster form on the internet.
It started with a few blue splotches on his hands, and on the back of his neck.
Then, the splotches began to spread throughout his body, to every part, and the spaces in between, like behind his ears.
By lunchtime, Rob's skin was completely bright blue, from the top of his head to the tips of his fingers to the ends of his toes.
When Rob went into the bathroom, he immediately noticed that his skin had turned blue, and stared at himself, jaw hanging. He looked like someone had pulled a prank on him and poured blue food dye into his shower head.
"OH MY." Rob said to himself. "I'm as blue as the sky."
The change in colour, it was surprising, but not as surprising as when he later found out that his penis had grown smaller. It was only slightly smaller, but even so, he noticed it.
