So, you know how the Teru Teru Bouzu effect can sometimes make it snow? Well, does anyone know what triggers this? The reason I ask is because I was in the music box room in the Bottom Garden, I turned on the effect, and I could only make it snow and never make it rain. So I left the area, tried it in the outdoor section in the garden, and again it snowed. Then I went back in, tried it again, and it STILL snowed. So I thought it might be a timing- based thing, so I went deeper into the Bottom Garden, tried it again, and it still snowed.
After trying it again in both Overgrown Gate and Tulip Lamp World and consistently finding snow, I decided it must be something that's constant across a dream, but is it random or determined by anything? Lips McGee (talk) 17:42, June 25, 2017 (UTC)
Technically the effect just toggles the map's weather effects, so if the map has a dedicated snow/rain setting it will toggle that on/off.
If the map has no weather effect setting for var042 though, it will take the sum of var044's value (random 0-255 each dream) modulo by 16, and then either apply strong rain, or if the value is 0 strong snow. It's very rare that it'd be snow though, the random dream value would have to exactly be 0 or a multiple of 16. LainIwakura (talk) 09:37, June 26, 2017 (UTC)
Wait... are you sure about that? I tried it in White Fern World, according to its page it's supposed to toggle between different intensities of snow as you described, but it actually stopped the snow and made it rain. Unless it has something to do with the fact that the setting seems to be set in an event (Which is the same as the Snowy Pipe Organ), but I don't think there ARE any areas which have snow as their dedicated setting. In fact, I looked in Map Properties and the option to set it wasn't even there.
