Well made and amusing
You did a nice job in creating something humorous about something so unusual as a fish parasite. Your artwork was good, especially during the close-up face views. The ongoing monologue from the CE sounded like Brooklyn truck driver - dry humor without caring about the response. Not too much in the way of sound-effects (a few here and there) but the voice track was good. Probably could use a little bit more interactive dialogue, but that didn't detract from the humor.
In addition to all of this, you also managed to sneak in some facts about the parasite, making the learning experience fun. It was a little off-beat, but as flashes go, very well made. Keep up the good work!
