This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
噇 is a rare character. It visually combines 口 (mouth) with 童, but the exact historical development is uncertain.
With 口 (mouth) beside 童, you might imagine a child's mouth, but the meaning is unclear, so treat it as a rare kanji with no fixed image.
For トウ, picture a child (童) with a mouth (口) saying 'toe': toe -> トウ, even though the meaning is uncertain.
