Espen holds down the button

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Recognising that the button itself is not in the best location for being able to hear the sound it causes, Espen initially tries to persuade Olli to hit the button for him, while he runs around looking for the item responsible. However, after Olli proves to be unhelpful in this regard, Espen instead uses a child's rocking horse to hold the button down. He does lose some time initially, by checking around inside the house for the sound, but eventually finds his way out into the garden and then pretty quickly zeroes in on the gnome. His total time was 6 minutes and 54 seconds, earning him first place.
