query: Who is Menw son of Teirgwaedd and what is his role in the hunt for Twrch Trwyth?
answer: Menw son of Teirgwaedd is a character who, before the hunt for Twrch Trwyth begins, is sent to verify that the comb and scissors are between Twrch's ears.  He transforms into a bird, flies to Twrch's lair, and attempts to take one of the implements but only manages to get a silver bristle, getting wounded by Twrch's venom in the process.
