Unexpected item in the pond

We have bought these wildlife friendly ponds to replace out current pond.  They have a special area underneath for frogs.  Unfortunately they only sell one orientation so they can't be put side to side.  

Anyway I was putting the cardboard waste out and it was cold and I hadn't put my shoes on.  My effort to clear my lines rugby style was a bit like Wales yesterday!  The bag nearly went over the fence and didn't find touch! Mr T was not amused!
