How exactly does it effect the egg?
I read some where that it made them hatch faster is this true?

Also, if it is, how many clicks do you need for the pet to hatch?

I believe it is something like 5 clicks increases the time by an hour.

otherwise the pet will hatch in 72 hours (three days)

hatch time is 72 hours. And yes it looks like every 5 clicks = 1 extra hour off hatch time. (I just looked over my eggs)

So in a perfect world, roughly 360 click would = a hatch.

but usually eggs receive between 2-15 clicks before their hatch timers run out.

Thank you both so much :)
