There is no I96 in Gardiner's sign list.
I refer you to a website which published your paper on G1:
It shows a list of the Gardiner 'I' set ... but no 4-legged snake, I'm afraid.
I invite posters to search for it: type Gardiner Sign list I96 into any search engine and you will notice that the I96 glyph is scored through in the search, meaning it could not be found.
I cannot give a phonetic value to a glyph which does not exist.
Perhaps your 4-legged snake should clear out before the situation becomes too embarassing to bear, leaving the door ajar for your hasty exit shortly thereafter.
