He saw the name Cerebus and remembered that it was the name of a dog with three heads, a snake around its neck and another for the tail.
"I’ll try this one on for size" he exclaimed.
He clicked the “on” button on the screen, confirming his selection before he immediately began to feel a tingling sensation across his entire body as black fur began to grow in. He felt something sprouting from his lower spine before looking back to watch his long and scaly tail extend well below his knee. When it reached its final length of about 5 to maybe even 6 feet in length, the end of Jeff’s new appendage began to form two eyes and a mouth. When its eyes finally opened, Jeff found that he could see the world through its eyes alongside his original pair.
"This is so cool!" Jeff said in awe.
His body began to increase in both size and strength to fit his new form. His hands and feet began transforming into paws, losing more and more of their dexterity every second. His face began to push forward into a muzzle as his ears began to lengthen and shift to the top of his head. He began to feel pain (if it wasn’t already present) on the back of his neck, after a couple of seconds he heard the hiss of the second snake attached to the back of his neck.
“I look like a bipedal dog with some snakes attached to it.” Jeff thought to himself.
Feeling disappointed that he was still vertical, he began to feel weakness in his legs as he was forced onto all fours. While trying to stand back up, Jeff felt his hind legs begin to shift into a more quadrupedal stance.
“Scratch that,” he thought to himself “I am no longer bipedal.”
Then Jeff’s shoulders began to ache, it wouldn’t be long now until his other two heads pushed out from his shoulders. One question crept into Jeff’s mind, would he be in control of the other two heads like his snakes, or would they have a mind of their own?
