i got a zygarde too. took me about 2 days to get it. wait... i think it did. 2 or 3 days. but i named it Squishy. after the zygarde cell bonnie found in the x and y series. but im stuck on the research now... i cant follow 3 routes seeing as either i can follow it and im too slow on the final pokestop, or i can follow it and i cant get to the end seeing as it just isnt on my route.
