In for questioning is Lady Muck in her knee-high red socks and purple cheerleader dress. I tried to give her questions I thought she could answer but she got each one wrong, and each time I turn on one of the numbers above her head. The 4th easy question didn't need to be changed as she was going to be gunged anyway.

Lady Muck had cleaned up after we filmed the little "welcome" scene and while I was in the shower getting clean, she was in the garden exploring the pool where I store the waste gunge from the tank.

Once clean I went to offer Lady Muck a cup of tea and found her face-up in the gunge pool wallowing around. It was so funny that it just had to be made into a video for everyone to enjoy.

There was a technical issue with one of the cameras in this scene and the video file was initially lost. After hours of hard work recovering the data I found a few seconds were missing, so I apologise for this and will be replacing the camera.

This time I've lined up my cheerleaders for a simple intelligence test, just a few questions to see how clever they are, and if they get the questions wrong… I think we know what happens next.

But to be fair and give my girls a chance to save themselves I asked a 4th really easy question – little did they know that the answer would be changed at the last moment to guarantee they got it wrong and ended up being gunged.

After being punished for failing the test they were stripped down to their bikinis and covered again in another tank-load of multi-coloured gunge.

For these videos the actual tank (the bit on top) has been rebuilt to be bigger and stronger, so there is more gunge per-tank in every scene, and it was filled to almost overflowing.

The photos are all original size and the video clips show the gunging from the front and above.
