In this challenge, your goal is to visit every biome, but with a twist; you have to stay there until you've bred at least one Nicheling with every ideal gene for that biome. I playtested this, and it's really hard at first, but it gets a bit easier later; I've only playtested up to grassland though, and I'm around day 150 without getting to go to the next biome so... it might take a while. This challenge relies heavily on mutations!   STARTER CREATION 1 or 2 pairs of Nichel
