Arthur season 1 was somewhat notorious for using public domain music and sound effects. Though it quickly switched to exclusively its own original music, Kate's cry first appeared in that season. The issue is that other shows may not be reusing an Arthur sound effect, but that Arthur used a sound effect that other shows were already using.

If you want to add that information to the page, you must first prove that this sound effect originated with Arthur.
