Doesn't matter if you do or don't. You can easily just switch to it if you don't AS LONG AS you don't stop on the happiness checker. You can go over it, just don't let it open. If that makes sense... If you're on Platinum, you can just avoid it all altogether. It's #15 and the happiness checker is #6, so yeah. Anyways, lol, after you collect the egg, just go to the coin flip app, flip it 10 times, and let me know what your results are. H,H,T,H,H,T,T,T,H,H is what you want them to be, so if you get those, then congratulations, you hit your spread.
