All manner of interesting creatures populate the sci-fi genre, though many of them aren't the kinds of critters you'd want to snuggle up to after a long round of fetch-the-pyramid-ball. However, there are a few outer-space fauna, the sight of which triggers an immediate cuteness overload.
Here are the top 10 cutest alien animals:
Tribbles - Star Trek
These are the quintessential interstellar fluff balls, the fuzzy stuff of pure nuissance, and the kinds of alien creatures that most Star Fleet officers love to hate.
Alf - Alf
Alf's retro cred qualifies him for the list. He's the kind of alien you can have beers with, then skin and use as a shag carpet.
Nibbler - Futurama
Nibbler is undeniably cute, commanding of authority, and an efficient little antimatter-pooper. What's not to love?
K-9 - Doctor Who
Sure, he's a robot...but he's a loyal, chess-playing pooch-robot. Plus, he sports a cold, wet laser-nose.
Salacious Crum - Star Wars
He's one of those ugly-cute kind of fellas. Kind of like a Chinese Crested pooch. Also, what's not to love about that infectiously sinister giggle?
Adipose - Doctor Who
These little marshmallow parasites might kill you...but, awwww, look how squishy they are!
Muffit - Battlestar Galactica
Muffit is a daggit, basically the BSG version of a dog...but really he is pretty much the original Furby (but way less creepy).
Experiment 626 - Lilo & Stich
Really, shouldn't every girl have an alien friend like Stitch?
Puckmarin - Flight of the Navigator
Puckmarin is cuter than a baby sloth. That's saying something.
Gizmo - Gremlins
Note: Not nearly as cute when wet. However, those huge eyes kinda make up for it. Just look at that face...who could stay mad at that face?!
