How to get a rainbow stack in Rumble World?

As most of you know, those rainbows grant fevers that allow you to battle and potentially catch really strong Pokemon and rarer Pokemon that are difficult to obtain. But is there a set way to farm these rainbow stacks like by going to areas were you already caught every Pokemon available or by beating a high tier boss?

Since rainbows are completely random, then rainbow stacks would be completely random. You sometimes get rainbows when you receive a high combo, beat the level in a quick time, capture new Pokemon, etc. Rainbows are very basic to get. To get rainbow stacks, you need to repeat this process a couple of times. Sometimes - after you get one rainbow - your chance to getting more rainbows is slight more difficult, but doesn’t seem impossible. The whole idea of these rainbows is random. Following more and more to get a total of 3 rainbows would take a lot of time, but you get use to it. There is not definite way to trigger this process. Just based on your gameplay.
