Japan is famous for their affordable bath bombs that will give you surprises after it dissolves in the water. Each of these bath bombs contains one little toy or figurine from a wide range of designs, including Pokémon or Sanrio. Some places even sell designs that uniquely represent different parts of Japan.
In my recent trips to Japan, I bought bath bombs that contained characters from "That Time I Got Reincarnated as a Slime (Japanese: 転生したらスライムだった件). While I know there are clips on social media teaching us how to identify which design each pack contains, I simply could not find one for this set. This might not be the first set as I found another video on another set.
Previous Series
Therefore, I decided to make sure I do not repeat their serial numbers printed on the pack. Thankfully, I managed to get the secret on my first try and subsequently completed the whole set over two purchases. This series/set features a slime on top of each character who sits in the Japanese bath tub. Here are the designs with the serial number.
2507-TS72-40 Shuna (シュナ/朱菜)

I bought the bath bombs from Don Quijote (or Donki). However, the prices and promotions may differ between each store. I paid ¥12,000 for 3 bath bombs (RP: ¥450) at one outlet while another outlet is selling ¥500 per pack without any promotion.
