Yeah, more or less. Turtle ducks are one of the cutest animals. They kind of look the ducks from other worlds, but with turtle shells.

The weirdest thing was when we met the Earth King one time, and he had his own bear. It was a completely normal bear, not a platypus bear or anything. That's one rare time that we saw an animal that wasn't two together. [There was also the owl-like Knowledge Spirit and his (literally) foxy servants, but Aang wasn't sure if spirits counted.]
