Yeah I bought the chocolate egg too, the more cookies you have the bigger the payout for it. I can’t imagine it being to much if you wait because I had 30 sextillion and all I got was 167 quadrillion for clicking it.
There’s 20 total eggs.
I got ‘wrinklerspawn’, which causes wrinklers to explode into 5% more cookies. I think that could really add up.
Chocolate egg gives you 5% of your bank, so you want to leave it in the store until you’re about to reset, then sell all your buildings, buy that, then reset. It also means that you’re better off not buying things in the end game just because you can, because you don’t get full value when you sell them back: It’s not worth it to buy something unless it’ll earn you ~3% of its purchase price in the time until reset.
I’m currently sitting at 19/21 eggs found, and of course Omelet (which increases the rate of finding eggs) is one of the two I’m missing. I’m pretty sure the other one would be Goose Egg, but I haven’t double-checked the comprehensive lists. And it’s really annoying that this egg hunt is keeping me away from my eldeer, but there’s an achievement for them, so obviously I need to find them all.
Also note that the “normal” eggs (chicken, duck, robin, frogspawn, etc.) increase a completely new multiplier, not the same one that cookies and heavenly chips give, so they always remain relevant.
Ah, Cookieclicker, the gift that keeps on giving.
With regular updates, this game is always going to draw me back. 
Is that a good thing?
And I just checked the full list, and there are 20 eggs (as chicagowhitesox1173 said), not 21, which means that Omelet is the only one I’m missing. Which means that it’s totally useless for anything except getting the achievement, but I still really want to get that achievement, for the milk and for the boost on next reset. Grr.
Oh, and I’ve got to say that I love the El-Ahrairah quote on the biscuit that activates Easter season.
So selling your buildings and maximizing the cookies in the bank gets you more HCs?
The omelette egg looks like a fried egg.
Yes, I finally got it! Now I can go back to hunting eldeer, just as [del]God[/del] mutant beholder Santa intended.
Woot! 100 sextillion cookies!
I broke it.
I have NaN cookies, CPM:Infinity, with Infinity Heavenly Chips.
I used my largesse to buy 1500 of everything, except for cursors, of which I have 3000.
I have yet to figure out how that happened, but since the world is my oyster I won’t complain. I caught a frenzy and the game done went nuts on me.
Happy Memorial Day!
I finally got 200 Antimatter Condensers (the last one cost 4.654 sextillion). So, an achievement for that. Four achievements for the Easter Egg hunt. One for re-naming your bakery. I got the Cat’s Paw finally this round. And when I reset, with ~+50% HCs, I’ll get two more achievements for retiring with quintillions and sextillions.
A true bonanza.
I’m having a balls-hard time getting all the eggs.
I believe the trick is to open your game in 10 windows or so and go through each window clicking wrinklers. Whichever one gives you the most eggs, that’s the save you continue playing with.
Got all the eggs. Now it’s just booooooring, building up to 200 prisms and 400 cursors. It’s taking longer than I thought.
Heh. I just re-started a couple hours ago, and tried this… And my very first window, the one I had originally, gave me omelet and five ordinary eggs. Yeah, I’m keeping that one.
I read you also get one for naming your bakery “Orteil”.
ETA: Yup, you do, I just tried it.
Meh, that is a shadow achievement, no effect on cookie production. Window dressing!
Now that chocolate egg is something else- I got 3 sextillion from it before my last reset by hoarding cookies and selling all my buildings. Not bad.
How much did you have in your bank?
Presumably, 60 sextillion.
And I just got the 200 AMC achievement earlier today.
I’m at 190 prisms. I kinda want to reset because I hear the last 10 are pretty tough to get.
Right. I hoarded ~15 sextillion and got ~45 sextillion out of selling all my buildings. Thanks to ‘egg’, with no buildings, I was still producing over 3 million cps.
Do it. Maybe reset twice. I only have 181!
