Mega Moon in GAG 2 mainly spawns Mega Seeds during the night event, and planting one can grow a random crop with a much higher chance of becoming a large variant. It does not appear to boost mega pets or add a separate mutation effect.

What it does

  • Spawns Mega Seeds around the island while the event is active.
  • Lets players race to collect them as they appear.
  • Turns the sky dark blue with a giant moon during the event.

What happens after planting

  • A planted Mega Seed can grow into a random crop from the regular shop pool.
  • Those crops have a higher chance of coming out big or huge , which makes them more valuable.
  • Some community guides mention possible random mutations, but the clearest repeated behavior is the larger crop size rather than a special mutation bonus.

Practical takeaway

If you’re asking whether Mega Moon is worth chasing: yes, it’s mostly a seed-hunting event that can pay off with oversized crops, especially on busy servers where more seeds can appear.

TL;DR: Mega Moon spawns Mega Seeds, and Mega Seeds can grow into random, bigger crops. It doesn’t seem to do much else.
