Janne blends his pineapple
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Janne blends the pineapple.
He purposefully wipes a small smudge of it on his shirt, hoping to throw Pilvi off, and then hides the pineapple in his rolled-up trouser legs, pockets, hoodie, and other clothing.
Pilvi only makes one incorrect guess before finding all of the pineapple.
