Diego blinked, his face suddenly a mask of confusion which he quickly slid off. He was a predator, he didn't show weakness.

But... extinct? Sabers... gone?

No. No, that was impossible. Mammoths could go extinct, easily - the only one he'd seen at all recently was Manny - and if all sloths were like Sid, they'd be extinct within two days. But not sabers.

With one last murderous glare at the human, Diego turned away from him and pulled up on the rock. He'd seen humans standing and walking before, he knew the basic motions. Slowly and carefully, he managed to stand on the bottom two paws, leaning heavily on the rock to keep his balance.

But it wasn't a rock, it was... much smoother. Just like everything else in the room, he hadn't seen it before.
