The Moon Dragon is a Prismatic pet in Grow a Garden and one of the hardest pulls tied to the Harvest Moon Event. It comes only from the event-exclusive Moon Egg, and its passive does two useful things at once by mutating your crops and pushing your pets up a level.
Quick answer: Hatch the Moon Egg during the Harvest Moon Event. Each egg has a 0.5% chance to produce the Moon Dragon, so expect to open several before it appears.

Moon Dragon requirements and drop rate
There is a single path to the Moon Dragon. You need the Moon Egg, and the Moon Egg is only available while the Harvest Moon Event is running. Because the pet is Prismatic, its hatch rate is very low, and the outcome is pure chance every time you open an egg.

You know it worked when the hatched pet is the Moon Dragon rather than one of the more common results from the Moon Egg. If you keep getting other pets, that is expected behavior at this drop rate, not a bug. The only reason it fails to appear is the low RNG, so more eggs is the only lever you control.
What the Draconis Luna passive does
The Moon Dragon’s passive is called Draconis Luna, and it works in two ways every time it activates. First, it occasionally mutates fruit in your garden with either the Moonlit or Moonbeam mutation, which raises the value of that harvest. Second, each fruit affected by the passive has its own chance to raise the level of a random pet in your garden by one.
That second effect is what makes the Moon Dragon more than a value pet. Over time it feeds free experience into your collection, leveling pets you would otherwise have to grind up manually.
Night-type pets scale the mutations
The number of fruits the Moon Dragon can mutate on each activation depends on how many Night-type pets you currently have placed in your garden. The more Night pets you keep active, the more fruits the passive touches per trigger, which also increases how many random level-up rolls happen. If you already run a Night-focused lineup, the Moon Dragon fits directly into it.
Is the Moon Dragon worth chasing?
Yes. The Moon Dragon is one of the strongest pets from the Harvest Moon Event because its passive pays off twice, adding Moon-themed mutations to your harvest while quietly leveling up your pet roster. The 0.5% hatch chance makes it a genuine grind, but if you pull one, it is worth keeping and placing, especially alongside a stack of Night-type pets that boost its mutation output.
