An Altered Genderless Shiny Giratina meets a semi-young Female Alien Cosmic Shiny Giratina. Both of them see love at first sight and go into the strange water. Their love is already showing through their kisses. Little that they know is the strange water us making them gain weight and grow fatter.

It appears the strange water is indeed, making them fatter. Not that they mind and/or are too busy loving each other.
