Today Paoli and Lucia, in their work as scientists, they are hired by Hikari to carry out a new scientific method that helps to lighten hair, for that the girls must prepare a new formula that helps them qualify for the test for which they were called, but Paoli, somewhat nervous that things will not go well, begins to search.

Other formulas are easier in her phone book, and she neglects Lucia, who feels confident that everything will be fine, and in a fright when Paoli speaks to her, a little more substance falls into the container and the formula spoils. The bad news is that Paoli had already called Hikari to understand that everything was fine. In a couple of minutes Hikari arrives and realizes the mess they made with that sticky substance, and a very annoying person makes them pay for their mistakes. Tying them up by putting a gag on them and throwing that disgusting substance on them, they deserve it, crazy scientists!
