Missing key

Zion was walking in the park ,looking for the right sized stick for her dog Sam. As she was looking she came across a key.  It was just lying there like no one owned it. Zion picked it up and whispered to herself “where did this come from ?”.  She stood up and looked around while her dog was running. Zion saw a shadow disappear into the bushes . She called “ is someone there? “  no one answered.  Her pet Sam ran into the bush and didn’t come out! She called once more “ is someone there?” no reply. Whatever would she do now?
