I can never watch this video and not laugh hysterically at the sheer cuteness and adorability
Oh, you bugger, I've got a laughter/smile combo headache from that now

Don't believe I've seen the full version before neither. What a total ball of huggableness.
Also, on a different tack, the "ninja baby" linked at the end of it is quite badass ... if you can get over the rubbish laugh-track pasted onto it.
BTW, Ace of Spades, your Pile o' Labs broke my cuteometer I think.
Also, Guinea Pigs and Hamsters. Come on. :3
Particularly baby guineas, and robbos. Anything that inoffensively manic is an automatic choice.
... have to say after rescanning the rest of this thread, that I don't often find that many cartoon things that "cute" though, with a few (unnameable...) exceptions. It's always just so... contrived, is the thing. At least babies/baby animals are naturally occurring. They're both designed towards the same ends, but at least in nature it serves a purpose other than getting more manchildren and broody girls to irrationally love your anime series (the grating voices don't really help).
In particular, much as DMFA is amusing, the mows are just amorphous blobs that are probably only that shape as it makes piles of them easy to sketch out; and the catgirls that have popped up in this thread so far have been just plain disturbing, especially the Grim Reaper one whose eyes go right beyond regular "exaggerated anime anatomy" (or moe-moe windows-to-the-soul or whatever) and deep into the bottom of the uncanny valley of "where the hell does her brain, olfactory sinus, or most of her mouth fit in between those mutant eyeballs?"... and keeps on digging. Seriously, if a baby human or other animal was born with those ocular proportions, its own mother would dash it to pieces on the ground out of fear or a primal urge to not waste precious milk on rearing something obviously unfit for survival.
