You flip to page 7, where you can find fountains to become. One of them catches your attention, which depicts a mermaid sitting in a rock and holding a vase which sprouts water. It looks beautiful, and you decide you're going to be like that.
You go where the receptionist is, and tell her:
"Hello, i've made my decision, and i'd like to become a mermaid fountain." you ask in a shy voice.
"Perfect." says the lady. "It's a cute form, i've spent a week like that and it feels wonderful. But I have to ask you one thing... for how long would you want to stay like that."

"No, you won't. You will have an everlasting magical aura that will protect you from all harm and will ensure that you spend the eternity as unbreakable stone."
This gets you convinced, and after thinking for a bit, you tell the woman:
"I've decided, i'd wish to make it..."
