Back home these are referred to as Gator's. Actually not just these, but any green box. I don't know why, maybe it's the color. Anyway I struggled to come up with a title for this so this is what you get. This is designed to fool muggles not cachers, but it will need your help to make sure it goes back properly so it will do just that. I can't remember if I put a pencil in the cache or not (it's been in my bag for weeks) so best if you BYOP.
Okay, so after reading the first log, it should be noted that you do not need a tool to extract the log. There is a cap on the bottom that is removable.
