Hall of Mirrors

You passed by a tent with mirrors presenting the entrance in a concave manner. As such, anyone that passed through it was reflected in a way where they were curved.

Uninteresting, you thought at first, but then there was a scrawny and lanky nerd that came in only to have a huge and buff person to come out, built like a tank. At first, you thought it was a mere trick, a coincidence that somebody had the same hairstyle, clothing, and acme-laden face.

Then a group of giggling girls came inside and you observed closely. Soon they came out with breast bigger than they were before with perfectly shaped assess, morphed like fruits.

You've seen enough and dashed inside with others. As suspected it seemed like any normal hall of mirrors, save for a fork with two signs.

One hung with "Inflation" scribbled on it while another said "Elongate."
