Nellie the Sea Otter, who rose to fame in 2012 for her cup stacking skills, has died at the age of 19.
Officials at Point Defiance Zoo and Aquarium in Tacoma, Washington said that Nellie was euthanized after acute illness.
Let's all hope she finds an otter friend to hold her hand down the big river in the sky.
R.I.P Nellie, we'll miss you.
