They're like naughty kids - if there is anything they SHOULDN"T HAVE - they'll find it!
They crack me up when they'r ein the "pond" - all can be CALM and one decides to go under and SHOOT to the otherside, then all hell breaks loose - then they ALL jump out run like crazy in one direction, turn back - run back to the pond and jump back in!
(sadly my make-shift pond made with a shower curtain is starting to crack - going to have to find another idea till we can get a proper pond)
