The Moon Cycle is a gameplay mechanic which affects the appearance of Werepigs and Woodie's transformation. Werepigs are normal Pigs who are caught outdoors during a full moon, and Woodie turns into a Werebeaver whenever there's a full moon.
Thecan be used to see past Day 18.
In all DLCs, several additional changes can be observed on a full moon. The moon casts down a dim, blue-tinted light over the world, so the player can safely explore without a light source and fear of Charlie. Mushrooms will turn into Mushtrees. Flowers will turn into Evil Flowers (But will revert back from the 3/4 Gibbous days onwards). The eyes on Pig, Wildbore and Merm Heads glow white, generate an insanity aura, and drop Nightmare Fuel when hammered. Ghosts will emerge from any type of Grave, including Watery Graves.
Full moons can also affect the Cave worlds. Unlike in the surface, the full moon does not provide light visibility to this world since caves are underground. Therefore, characters are required to have a sufficient light source while spelunking. Just like on the surface, the screen tone will change into a bluish color much like in Winter. Mushrooms also have a chance of turning into Mushtrees, Pigs will turn into Werepigs, and Flowers will change into Evil Flowers when in a cave.
In HAM, during a full moon, Pikos and Orange Pikos will become hostile to the Player, as well as give off a small amount of light if kept in the Player's Inventory. Similar to Woodie, the full moon forces Wilba to transform into her Werepig form. During the Aporkalypse, the moon icon that shows the player the phase of the moon will be constant, showing a reddish moon, and the changes of a full moon will also be present.
In Don't Starve Together, a full moon only lasts one day. The first full moon occurs on day 11, and then it occurs every 20 days - on days 31, 51, 71, etc. Likewise, the first new moon occurs on day 1, and then it occurs every 20 days - on days 21, 41, 61, etc.
In DST Woodie has two additional possible transformations during the full moon: Weregoose and Weremoose.
|2 - 4||Quarter (Waxing Crescent) Moon|
|5 - 7||Half Moon|
|8 - 10||3/4 (Waxing Gibbous) Moon|
|12 - 14||3/4 (Waning Gibbous) Moon|
|15 - 17||Half Moon|
|18 - 20||Quarter (Waxing Crescent) Moon|
|21||New Moon (Next cycle)|
The moon cycle does not affect the caves and is not present in the caves.
- By default, it takes 560 days for the beginning of the Moon Cycle to re-align with the first day of the starting season.
- When both seasons are set to "Long", 12 complete moon cycles will occur in 4 seasons' time (similar to a standard calendar year).
- With RoG, if a full moon occurs in the fifth Adventure Mode chapter "Darkness", everything happens as per normal (blue tint, Evil Flowers, etc.). However, it remains completely dark and a light source is still required.
- Since the Return of Them update in Don't Starve Together, the moon has a crack in it.
