Look what I found in my skimmer

[mc-cro]

I went to clean my skimmer last night, and when I pulled off the collection cup, I found someone had beat me to the punch!

I have no idea how long he has been in there, or how he got in there. The only thing I can think of is that he actually worked his way up through the exit pipe, all the way back into the chamber. I wouldnt think he could fit through the bottom where the skimmer chamber meets the exit pipe, but apparently he did.
