Can the pupil become the teacher? Brook is loving Splosh School and her next assignment is to show splosh instructor Jess how much of a "dirty girl" she is in a bid to gain her Diploma.

Both girls are wearing matching green and white dresses to match the green and white gunge as Brook quickly gets down to the serious job at hand with some dirty talk and slime assisted hand relief.

Let's hope Jess gives Brook top marks!
