ADVICE PLZ!!!

My poor foster son has been having a whole break down. He went to the skate park with my 17&18 year old son's yesterday and they started making fun of for being afraid of the dark and sleeping with an Elmo plushy at 14. His mom gave it to him when he was little and she died so he carried it around everywhere but usually hides it in his backpack. My oldest took it out his backpack and threw it over the fence to the country club. Just know if you saw my other post you know my boys are being punished and just lost their ENTIRE summer. The country club was close so I had to call today as soon as it opened to let them know the situation and if I could come get it. They said they could look for it but maintenance usually comes before it opens so it may have gotten thrown away. Fuck! Just fuck fuck FUCK! My foster son is beyond hurt and I do hope they are able to find it and idk what to do if they don't because he refused to even try to sleep last night even with his lava lamp. Idk what to do. Let my boys know they better hope they are able to find it because if not they won't have phones the entire summer either and I'll make them have flip phones for the school year next year. But the advice I need is what to do about my foster son. He's has that for YEARS and even brought it with him to school. He just kept it in his backpack and he is so sad.

Edit: Thx guys. I'm sending my boys down to look for it tomorrow. I told them they aren't coming back without it until it closes. They will look for it from the moment it opens until the moment it closes. I'll pack them water and some sandwiches and that's it. The sooner they find it the sooner they can come home. The manager was extremely understanding!
