Doug the tickle monster tickled his wife and daughter with his tentacles.
but there was more to his tf than he knew:
since he was now a tickle monster, he could change other people into monsters by tickling them.
He focused his tickling on his daughter, and tickled her more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and MORE!
SUDDEN;LY!"
Sami began to change right before his and his wife's eyes:
Her dark brown hair became red and scaly.
her skin turned purple, and her top turned into pink scales, and her jeans became blue scales.
Tufts of green fur grew above her feet, which became webbed.
Her hands became tentacles.
She gained a third eye in the middle of her forehead.
"Oh my!" Jessica said.
"Now I'm a tickle monster too!" Sami cheered.
