shiny hunting is bad enough, and i made a simulator. have fun. Press space/click the gyarados to increase your encounters. the odds aren't EXACT because decimals won't work in scratch. In this project i've used the generic gyarados to represent the pokemon you're attempting to get a shiny for. Credits to Pokemon for the pictures hehe I've held the space button and missed a red gyarados more times than I can count now.
