Dear Mad Seagull Lady,
We know you hate Seagulls but I think it is a touch paranoid to think your daughter has been possessed by them.
She was only pretending a banana skin was a seagull, it actually shows clever imaginative play rather than possession.
Keep on hating the seagulls though, just try and be less paranoid.
Love
