though evidence to back up these statements can be hard to come by (no one's word is sacred anymore

) i beleive i have encountered a situation where i did not realize shroomie was breaching and i took off running which scared her off...
it inturrupted her animation and sent her diving prematurely...
shroomie has appeared to me on the ledge on the other side of the shroom w/o having fed her (or the flapers more precisely; i think i can hear shroomie's call when i pull the lever which might be what attracts her if not the spores)
she has also appeared w/o having fed her upon stepping onto the metal walkway. she has only ever appeared to me once per trip (if at all) but i joined someone in his newly opened teledahn and he was getting shroomie to appear repeatidly every four or five pulls of the lever...
i'd like to think running instead of walking makes her more unlikely to appear, even on the metal walkway leading past the power tower, but i am not sure if there is any indication of this... i still don't know what the feeder on the wooden walkway to/from the slave caves does if anything... the dynamics of shroomies behavior are quite complex and this thread has renewed interest in trying to figure some things out...
if what Sharper writes about in his journal is anything similar to shroomie's bahavior in response to explorers actions his journal would make a good source for information... i beleive he writes of having to move slowly when he was in the process of hunting her...
