Have any idea how to clean these big mouths with ginormous chompers? Look and see how it's done on this willing (not-so-willing?) model named Orien.
How Do Pygmy Hippos Measure Up to Nile Hippos?
If you haven't yet ooohed and ahhed over this baby hippo, the newborn from the Netherlands is actually a Pygmy (like Monifa), which is different than the standard-sized Nile hippopotamuses. Obviously the Pygmy hippos are much smaller (and rarer), but exactly how much smaller and rarer? Find out when you take this quiz!

Hello There Hungry, Hungry Newborn Hippo!
I spy lettuce, carrots, and cucumber chunks for this baby hippo and proud mama. Did you know that hippos eat just about 1 percent of their total body weight as adults? Don't call them greedy, though — if necessary, the huge mammals can store two days' worth of grass in their tummies and go up to three weeks without eating.
There's a whole buffet laid out here and no need to gorge, so check out one more picture of the grazing babe when you read more
It's Swimtime For Berlin's Baby Hippo!
Although it isn't Monifa (who's currently a close second in our cutest zoo baby of '08 poll), this equally adoro hippo is having some watery fun with mama, Kati, at the Berlin Zoo! Born less than a month ago on Nov. 29, it makes sense that the yet-unnamed babe can already swim since many hippopotamuses are born underwater with the mom pushing the lil one to the surface to breathe, and even nursing while in there.

Hooray For Hippo Playtime With More and More Monifa!
Well, well, well, isn't Monifa already quite the little media darling? I was already drooling over her piccys, and now this video. Just. Can't Handle. It. There's simply too much cute here for a Friday afternoon – watch her dunk herself underwater (!) below.
Meet Monifa: An Adoro One-Month-Old Pygmy Hippopotamus
Well looky here, baby! Meet Monifa – just one-month-old and already ready for the spotlight. It's shining brightly, too, as she's the first Pygmy Hippo born at Sydney's Taronga Zoo in the past 23 years . . . but don't worry, her cuteness makes up for lost time. I love baby animals (especially hippopotami) and, although this lass will eventually make a splash at over 350 pounds, she's about the size of my dog now.
There are plenty more pictures – bathtime, playtime, lil hippo teeth, lil hippo tail – so check them out when you read more
