So the sound effect says 'deus ex machina,' but this does actually get explained later on. I have have had trouble with subtlety, but I wasn't that bad. XD
Let's see... the blue Kirby is quoting Lion King in the first panel, for reasons that I'm sure made sense at the time I made the comic. And considering Blue is running from those zombies, and they seem to be keeping pace with him, those are some fast-moving zombies. I am fond of that last zombie who's obviously struggling to keep up.
