That pygmy hippo baby was on the evening news here. Sooooooooooooooooo adorable. At one point it was munching on the zoo-keeper's radio tucked behind her waist-band.
I'm a big fan of Tamarin monkeys, both the Golden Lion variety, and the Cotton-top variety. The adults are no larger than the size of an adult male human hand. Most videos don't convey how tiny they are, and thus how amazingly cute.
This youtube link shows twin Golden Lion Tamarin mokey babies. They would be no larger than a human man's finger... as long as it was a
fluffy finger.
Linky: watch full vid for the cuteness. To give you an idea of size, there's a tamarin monkey sitting on this man's shoulder right from the start of this 30s video. Look hard to his right, otherwise you'll miss it! http://au.youtube.com/watch?v=swsSGFN55xs&feature=related
And this is an adult Cotton-top tamarin here: http://au.youtube.com/watch?v=FZ2PZ0oBXSA&feature=related
