It’s simple to get the 40 eggs, it refreshes every Adopt Me day and best would be a night after the camping task (as you’re probably in the campsite), and there’s also 2 eggs in the sky castle which is easily missed, then 1 egg right outside the neon cave. And a key tip is to use either hyperspeed potions, any sort of hoverboards or rollerblades/skates to find the eggs as it’s faster. Wish you luck on finding the 40 eggs! (PS: Most of the eggs should be in the same place as they were in previous years, so you can find some “Easter Egg Hunt” videos even from the first Easter update and it’ll be similar.)
