WHERE & HOW TO FARM
Where to farm
A regular Merchant in Moongolow or another stage where available; Eggman in Moongolow for bulk purchases; Moon Guardians for direct drops.
Golden Eggs permanently improve the character you play, so choose your recipient before spending. Regular Merchants sell eggs for gold, Eggman in Moongolow offers bulk purchases when available, and Moon Guardians in Moongolow drop eggs when defeated. These are separate ways to make progress toward a character investment. Check that the intended character is active before collecting or purchasing an egg, then reassess your next run after the upgrade takes effect.
