The Animalcolm Games

Rainbow was an ordinary dolphin, living a normal life until one morning she wakes up in a big room with a lot of bunker beds. With the number 253 printed on her dorsal fin and her BFF Ivory who was number 257, they go through series of games to see who will get 100,000,000$. But here's the problem: there are thousands of other Animalcolms who have powers of the elements in their blood who are competing against one another to get the prize. Rainbow was Water-type and Fairy-Type. Those who are eliminated, will sit by the side and watch the remaining participants as they play the games. Will Rainbow get eliminated, or will she get the prize?
