You may remember that Katy's interview finished with her completely destroyed and heading for the showers (& we get a short recap of that clip to set the scene). This new scene picks up where that one left off, as Messy Ma and Ana laugh and congratulate each other on having totally trashed Katy.

However, they are interrupted when Katy returns and says she has a question: How is she supposed to learn how to dish out the mess?

Ana says she shouldn't worry, they will organise for another girl to come in for her to practice on next time, but naughty Messy Ma interrupts and says there's no need to wait, she can practice on Ana right now.

Ana protests and pleads, but once Messy Ma has made up her mind, there's no going back.

Messy Ma can't resist the opportunity to "teach" Katy how to dish out the mess, by doing several of the slimings herself, and then getting Katy to show what she's learned. All of which means poor, begging Ana gets covered in different colour gunges, and then takes melted chocolate, pies and cake too. She is completely covered and Messy Ma finds it hilarious.

Poor Ana!
