Espen is smart, but not quite smart enough

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

Espen's eagle eye spots the information in the task brief about how the time is calculated, so he calls out the phrase to signify he has completed the task almost immediately, without putting any hedgehogs in the enclosure. His rationale is that any length of time multiplied by zero hedgehogs will come out as zero seconds, winning him the task. What he forgets is that it is not possible to fill an enclosure with zero hedgehogs - there must be at least one present. He therefore fails the task, despite his seemingly smart solution, and earns no points.
