Show hidden objects

I have the same problem. I've been playing since the game came out and I could have swore item spawners were in there and a lot of other types of public lot items. I can now find a whole stocked fishing pond in showhiddenobjects, I found it by looking at the name of the one at one of the parks. But I definately could not find the ones for spawning any kind of effect or collectable or anything. Also I THOUGHT "bb.showhiddenobjects" used to give you a response about it being activated like several of the other ones do, but I haven't seen that in awhile either. 

Thankfully I found a mod made by someone recently that makes fish ponds and frog logs buyable items in game normally now. So I can make my swamp themed backyard now. :D
