Had to pick a short clip of an animation and identify 3 examples of the 12 principles of animation.
The choice was Pixar Animation Studios' 2003 film "Finding Nemo", distributed by Walt Disney Pictures, and directed by Andrew Stanton.
First example was Squash and Stretch, the pufferfish, at 0:02.
The second example is Staging, Marlin (Nemo's dad) sees Nemo dead in the plastic bag, at 1:27.
The third example is Arcs, Gill gets shot out of the volcano, at 2:03.

Other examples of Squash & Stretch are the plastic bag Nemo was in, at 0:42 and other various parts of the scene. And more pufferfish at 1:57.
