Fronk's Formed Fish

"Fronk's" was a brand of fish nuggets. A "Fronk's" advertising board makes an appearance in the Mythic map Longshore[1].
The name Fronk could be a reference to the meme Woll Smoth, where all the vowels of a word are replaced with "O". This is unlikely, however, as there is not a widely-known brand of fish nugget's called "Frank's", "Frink's" "Frenk's" or "Frunk's".
