The passive symbol is the logo "K , D , A" and for each stack, one music note plays, until he reaches full stack, a snippet of a song can be heard.

When he eats an ally/enemy, they can hear some EDM music with a low pass filter (Aka the “outside a club” effect.) Tahm and allies can pick between tracks. Better watch out, Madam Kermit can serve some chart-smashing banging bops in his belly.
When he ults, nearby enemies hear the build-up from POP/STARS and once he arrives the song chorus briefly plays.
Now he's not the only one starving ♥
