It's the biggest and most stupid mammal of South America [if you exclude H. sapiens, of course] Capivara is the rodent. BTW, both are used as methaphors: _anta_ means very stupid, _capivara_ means a bad chess player. FWIW, the first animal I thought of when I read the description was the capybara (even though I was not aware that they got to be as large as cows, which is one reason why I didn't say anything at the time) rather than the tapir . . .

I tried a training wheels approach today - just pushing him slowly forward, not letting him hold on to me - and he squealed with glee. So any day now I bet. Verbally he's a whiz with dhat (for what is that thing I'm pointing at?) and muh muh muh (for I'm hungry and/or I want mommy!) and he seems to consistently say dah! dah! when I get home.
