What Happens to Isabella in Moon Farm? Why can't she talk? Was Alyson Stoner sick? Why is she a background character? Well your about to see AND DON'T RUIN HER Isabella loses her voice and can't talk when she goes to the Moon She has Astrophobia when Bufford hits Baljeet on the balls off-screen so she watches in horror for that and then she later has a good time dancing with an Ice Cream Cone and then she looks around suspicious about where the Disembodied Reggae Space Voice is coming from
