Munya's brush tail
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Munya chose a pipe-cleaning brush as a tail (though he believed it was a toilet brush, for some reason), and created a path for himself to follow using rope and pipes. He followed his path perfectly, and rammed the brush up the tiger's backside after 2 minutes and 6 seconds, earning first place.
