The Shedd Aquarium put up a new video of its newest star, known only as Pup 681, yesterday, after its first round of pictures and footage started going viral.

The pup swims in her own pool, splashing with long strands of felt normally used in carwashes that are intended to replicate kelp. She also chews on plastic key rings and other toys because she is teething, her trainers said.

The pup's caretakers said she is learning to feed and bathe herself. She currently takes in a diet of instant formula in a bottle and sliced clam pieces.

The pup will stay at Shedd indefinitely and eventually will join four other otters in the Regenstein Sea Otter habitat.
