Love your "side stories"! I'm so glad you found your dumpster-diving Dreamsicle.
I'd imagine she was drawn in by some lingering aromas? Funny what a motivated snake can do...
BTW, I feel for ya...that used to be me when I had a house-full (& I do mean FULL) of snakes..."staggering around from exhaustion". I'm old enough to know better now. I do still miss having rattling roomies, but it's very nice just having a few pet rat snakes these days in terms of upkeep.
