It all starts with Gil apologizing to Johnny for not going on his birthday, Johnny says he got a rocket skateboard for his birthday, and he takes it to the lab to see. Meanwhile, Susan and Mary, made a mix that they had never done before and decided to find out what she does, but noticed that she seems unstable, and agreed to be very careful when holding her. Without them noticing Johnny enters the lab and when he picks up the rocket skateboard (which was there because they were present) he accidentally fires it, and he fires and hits their container and an explosion happens, and when they notice they realize that their bodies were left different (you must know an old episode in which the two transform Johnny into an attractive teen girl, but they don’t use them on themselves because he became a monster later, my idea is that they got bodies like that only without the second transformation and the first being permanent). And when Gil notices them immediately he asks excitedly who they are, and when Johnny answers that they are his sisters, he as always says he didn't know he had sisters, and asks if the two of them have any plans for tonight, Johnny he approaches and they ask him if it is just an impression or after so many failed attempts to impress Gil, they are managing to attract him by accident and he replies that he thinks so. They immediately reply that they have no plans for tonight and that the two are free to meet with him. And Johnny said that he lets Gil show the skateboard tomorrow and that he helps them get ready for the meeting, when Gil leaves they ask Johnny if he is serious, and he said he just played that if they finally get it this time, you’ll never have to wear any dress or makeup, or anything feminine they want to test on him, stating that he only accepts even the other tests.
