The Smurfs is the Western Animation KING of this trope; frequently occurring whenever someone leaves, goes missing, or suffers a Disney Death, or just at the drop of a hat in general. Notable Disney Death examples include "Clumsy Luck" (with Clumsy) and "Smurfquest" (with Grandpa).
In Smurfette's debut episode ("The Smurfette"), she cries in remorse after nearly flooding the village, confessing about being a creation of Gargamel's, and laments that she deserves to be punished for her actions.

Occurs twice in the episode "The Abominable Snowbeast" during TWO (yes, TWO) Disney Deaths.

Later during the episode when everyone is cured, everyone cries again when Weepy (having been captured by Gargemel) is supposedly killed off. (Interestingly, even though the episode also focuses on Hefty learning that it's OK for a tough Smurf to cry, he has cried before in previous episodes, including "Hefty and the Wheelsmurfer" as well as the ones mentioned above.)
