After not seeing it for 20mins, I began to feel a little anxious and looked for it everywhere.Later, i heard the familiar  bark with the background music in the near distance, with the funny song--<Happy tree friend >, I rushed to there,  Seeing it shout at a yellow animal shape things and wagging tail from distance, I breathe a sigh of relief when fund it’s in the nearby, it’s okay, I'm glad it didn't get lost or caught by a dog dealer. Remembered the fat man who live upstairs had been lost his dog, it was a five years old Huskie, and it’s really cute and beautiful, so i was really afraid to lose my dog that time... It just glance me and then continue to bark to small animal with wagging tail. It’s action with funny background music make me don’t know whether to laugh or to cry. As I got closer, it turned out to be a small yellow squirrel shaped land speakers, the sound quality is pretty good, can be heard in big area and very clear, in the meantime, because the surround building make this park being a small basin, the music there is a stereo sound, and even have the feeling of wearing headphones sound effects.The little squirrel shape, appearance is really cute, has a yellow waterproof casing, hidden in the green grass, make the grass more full of lively, it’s not abrupt at all and nature be in harmony are an organic whole, You can't find it without looking at it careful, It also labeled the brand of OBT. I guess it was excited for hear the evil music from the little squirrel.
