Atm, I’m collecting only the ones that I really like, but maybe down the road since I do like the idea of having as many different collectibles (egg or not) as possible.
The eggs that I have are: lucky cat (still need to redeem), starlight, starry night, Galaxy, Ditto, Turquoise Squid, HHP, Fossil, Froggy Chair, Sweetheart egg, moonlight, cobweb, gastly, boo, will o wisp, galaxy.
I did have prismatic but I sold it to a friend years back. I had a red pikmin but gifted it to a friend.
The ones I’d like next are: stardust, nightmare egg, aurora egg, mt. fuji, frost egg, maybe the eye egg, splatoon egg.
Also I’d like more of some that I have, particularly lucky cat, will o wisp, ditto.
