Mega Moon in GAG2 spawns Mega Seeds during a night event, and those seeds can grow into much larger versions of normal non-limited crops. It does not appear to add a special crop mutation or boost beyond that, based on the latest guide coverage.

What it does

  • A huge blue moon appears at night.
  • Mega Seeds spawn around the island.
  • Players race to collect them before someone else does.
  • Planting a Mega Seed can produce a large variant of a crop.

What it doesn’t do

  • It does not seem to apply a special mutation like some other moon events.
  • It does not seem to be related to mega pets, according to the current guide notes.

Quick scoop

In plain terms: Mega Moon = more Mega Seeds = bigger plants.
