So after my massive trial session I can tell you what seems to not matter.
1. Speaking into the mic is not needed, just have the mic on.
2. There is no need to zoom in look at objects. I basically never R3ed anything last night and got it about 30 times.
3. You can beat it possessed or not possessed.
4. You can get giggle during and outside a haunting though it seems to happen during hauntings more.
5. Everything involved with Lisa, where she is, what she was looking at, what noise she makes, etc. does not lead to a any consistent pattern.
6. Since you can get the giggle while possessed, when lisa does not haunt anymore, it shows that where Lisa is is not really the key.
7. You can get the giggle while standing, walking, or paused. I have walked into a giggle before. I got a giggle while being eaten before (which leads to the theory that lisa's actions are completely independent of the second giggle)
8. Stuff like the picture pieces, the colored lights, and hidden messages mean nothing to getting the giggle.
Here are things that seem to increase your chances for whatever reason.
1. Going to where Lisa was last does seem to be a good strategy as this is probably the most consistent way of getting the second giggle. Though I feel this is more to due with spots than Lisa.
2. There definitely seems to be trigger spots these are areas where the 2nd giggle occurs frequently. I think if you consistently stand or move around these spots you may get it. Spots where I have gotten a giggle are:
- At phone
- At mirror
- Outside bathroom door in hallway (or the second outside window if you want to look at it that way)
- In hallway right before the hall opens to the radio room
- At radio (can also be picture)
- In basement
- At the entrance (where the loop begins) while backed against the door
- In the hall of the entrance but close to where it opens into the clock area
3. Whatever triggers this somehow can be activated by doing nothing but standing in one spot at times. Because this is possible it basically rules out having to do some sequence of events and seems to be tied to a TIME and PLACE.
4. For sure have your mic on, as far as I can tell it is required.
5. It is entirely possible that the requirements of getting the second giggle change. Strategies work consistently at some points, other times it stops working.
6. Hauntings last EXACTLY one minute. The intervals between hauntings change. I have no clue if this means anything.
Thats the best I got.
