They Might Be Giants - Here Come the 123's and something piqued my interest enough for me to engage in some Google-based research.
The fifth track of the album, entitled 'Triops Has Three Eyes', regales us with a diddy of what I previously had thought was a mythical creature (or at least long expired). Hereunto, the only three-eyed creatures I have been aware of are are that alien from Toy Story and Blinky, the toxic fish from The Simpsons. However, my extensive research (typing 'triops' into the search box) has shown that not only are these babies real, but you can also breed them at home.

And if you have not yet familiarized yourself with all the useless junk in the Think Geek catalog, may I suggest that you do so.
Move over Sea Monkeys, there's a new (well, technically not new) creepy aquarium creature in town.
