This is a normal font, well if you think of normal as aliens living among your font. These aliens produce air from their heads that gives the surrounding letters a bubbling rash that grows through time, you can tell what letters have had it the longest. H was the first to be infected. L coughed unknowingly runing H's healthy lifestyle. Obviously G caught it due to the proximity of the two. I'm not sure which letters are the monsters, i'm not sure if we can save the unaffected letters
