Poundland Motion Sensor Frogs

We have five of these Poundland frogs in my garden, all placed strategically in the flower beds.  They are BRILLIANT because when you walk past them, they croak!!

If Darrell and I run very quickly down the garden we can set them off croaking all at once, which makes next doors dog bark too.  I am sure I can identify each frog by their croak, as they are all have a slightly different pitch.
