Our garden has a number of naff things in it, chosen by the GC who adore them: 3 little fairies (they all have names and woe betide anyone who moves them from their homes!), 3 gnomes whose hats light up, a stone cat, and assorted tortoises, guinea pigs etc. - and a squirrel with 4 broken legs - great for playing vets! They are hidden round the garden under bushes and the children love them all to bits.
The only downside of the solar ones is that when the days are sunny enough to power the lights, they are also long enough that the lights work only long after the children are in bed! In the winter there is barely enough light to get them going!
