How cute! We usually have toys all over the backyard too! Only the culprit is my rescue Beagle, Shelby. She stratigically places the stuffed animals (and there is a toybox full!) all over the backyard. But she does it mostly when we are not at home!! I have caught her redhanded Or i should say mouthfull a couple of times. She looks so funny, because she will stand real still as if she is thinking that i might not see her!! LOL
