I'm very sorry to hear of the unexpected loss of your Megatron.
You have my deepest sympathies. It's never easy to say goodbye to a much beloved pet, especially when they leave us so suddenly. Time will heal the pain you are feeling and soon the memories of the good times you had with your budgie boy will give you comfort. Megatron will always live on in your heart.
Rest in peace, Megatron. You were much loved and will be missed.
