You mean Arctic Hare? Yes, very cute. Like giant snowballs. :3
A pacu? A pacu is an omnivorous freshwater fish hailing from Brazil (more specifically, the Amazon river basins) that is related to piranhas (though it is much less aggressive). Being omnivorous, it eats both plant and animal matter, and therefore requires a special set of teeth that can cut through both pond reeds and small prey with ease. Hence the freaky "human" teeth.
I personally think they're both cute AND creepy.
Mouth closed: "Aw how cute. It's just a big, fat, derpy-looking fish."
Mouth open: "OH DEAR GOD WHAT MAD SCIENCTIST CREATED THIS MUTANT MONSTROSITY???"
