Pokémon X and Y Playthrough Discussion

So I was chaining Goomy and then this weird music other than the regular PokeRadar music started playing. Sounded like I was running out of time. I didn't see a shiny patch either.. If this meant I missed a shiny patch and a potential shiny Goomy, I'm going to be one sad hunter. :c

This reminded me of the time I was playing Megaman Starforce 3 and wasn't aware of Omega level bosses rarely giving an ominous music to the area they inhabit. I was so scared I exited the Wave World only to research it 3 minutes later and realize I missed an Omega boss.
