Richard fails to drive a rat

Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!

Richard initially tried building a tunnel for the duck to go down, before he found the key and the rat remote control in the caravan, taping the duck to the rat and driving the rat towards the pond, but missing several times. He got the duck into the pond after 24 minutes and 20 seconds.
