Moo-ving on from mincing Marco's exit from Big Brother, the remaining housemates are being transformed into cows and farmers.

The group were gearing up for a pastoral fancy dress challenge - with a nasty sting in the tale.

The contestants were being split into two teams with one group dressing up as cows to be guided round a course by the other group playing farmers.

But the cattle were to be blindfolded and the farmers were only able to direct them using a device giving off a small electric shock.

The cows would have to negotiate manure, rotten vegetables and egg hazards littering the course.

The prize money currently stands at £74,000 and £2,500 will be saved for every cow successfully guided to the cattle pen.

The latest bizarre challenge to face the housemates follows the eviction of Marco Sabba.
