Miss Piggy should work, LOL I have a little ornament that when you rub a stick on it it sounds like a frog? Well ..... If he's still in there, "safe to swim?" is a good question. It's discussed in at least 198 threads when you search TFP for
dead animal. Many seem to focus on removal and then shocking. All point to testing and maintaining free chlorine & proper chemistry. Was it alive when it went down there? Keep checking skimmer to see if he came back up. Maybe turning off the skimmer for a short time to see if that helps with re-emergence. I might be tempted to konk another frog over the head and drop in a bucket of pool water to monitor decomposition time. I get tiny dead frogs all the time (and occasional gecko) - I remove them and pretend it didn't happen, while of course maintaining chemistry. For more humane and long term prevention, some folks use a frog log so they can climb out, eg
this on amazon. I still like the idea of a hand-operated drain auger (with pump or skimmer off). Or if you cut the skimmer pipe someplace back by the equipment pad maybe one of those "can-o air" drain blasters would force him out. Or a large version of a drain king
like this? Not sure how effective those are given the long pipe, and don't let it break off and slide down the pipe like one guy did.. Checking diverters and check valves good ideas too from
