Jenni chops up her pineapple
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jenni cuts the pineapple into multiple pieces and wraps them against various parts of her body using cling film.
She also uses a piece of the pineapple as a hair tie, and hides some of it in her shoes.
She manages to make Pilvi guess incorrectly 10 times.
