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)
