With the pebbles (in-app currency) you collect together within the app, you can buy various items to decorate little EggMon’s room!
Head over to the shop and select your items from the various themes available.
Keep your eyes peeled for the seasonal themes only available for a limited time!

Horrible. due to your app technical glitch, i lost 101 days progress. all you guys gave was 200 pebbles. i don't want pebbles. i want my 101 days progress back. due to your bug, i am now back to day 1 progress. that is just BS. Terrible. if i could give 0 stars i would have.

I rly love this app, I've been using it for 3 years now. My only complaint, and it's a significant one, is that it's not well optimized. The app is very slow, sometimes it doesn't work at all, and occasionally it completely freezes my phone. I don't know if this is a me problem, but I don't think so, because all the other apps on my phone work perfectly fine, even heavier ones, like TikTok for example.
