Is that the plug from one of those little plastic tanks??? It isn't supposed to be there that is for sure! I suspect it is the plug from the bottom of the tank.

The only other option I can come up with is packing to protect the spike when it was in packaging so you didn't poke yourself on it or something???
OMG! Bobbi, you may be right! it would explain the massive leakage from the plastic tank I tried yesterday..
As far as the spike, yeah, no that wasn't there the first time, I remember cause I stabbed myself with it, ya know us kids, "is that sharp?" *poke* "yep, it's sharp alright..where's the nearest hospital again??"...
Anyway Bobbi, did I ever tell you that I genuinely, whole-heartedly love you? Thank you again!
