Karin hides a teddy bear
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Karin's first question, upon reading the task brief, is whether she can cut the teddy bear up. However, she apparently thinks better of it, and decides that she wants to hoist the bear up into a tree, out of Olli's line of sight. The result of this is that it appears she has lynched the bear. The bear actually turns out to be very visible, from many positions around the garden, and Karin is painfully aware of this fact, but Olli somehow does not notice it until he is pretty much directly underneath it. In the studio, Olli reveals that it took him 5 minutes and 52 seconds to find the bear, putting her in fourth place.
