lol I was focusing just on the first part and didn't even pay attention to the ending.
That being said though: when I was fostering for the cat rescue, flees were a really big deal for the young kittens and some did die due to the fleas (condition called flea anemia - google it). I guess those fleas didn't spent enough time strategizing or they had miscalculated their budget. Or maybe they figured they could just hop on the next critter when this one runs out.
In which case it might actually be pretty similar to the lion eating a gazelle. Maybe if gazelle's could just drop a leg and regrow it the lion wouldn't have to kill the whole animal and could just eat that spare leg! ;)

Anyway I am ready to vote for that awesome goby!!!
