I think it's popular because it stirs up emotions. People are drawn to the sadness of the baby panda and feel a connection. Plus, the unique way it's presented in the cartoon makes it stand out.
The popularity could be because it brings a sense of joy and light-heartedness. Also, baby pandas are always a big draw, and a sneezing one adds a unique and charming element.
Maybe it's just tired from playing all day.
Maybe the baby is sad because it lost its favorite toy.
It could be waving to attract attention or express friendliness. Maybe it's just having a fun moment and waving randomly.
Maybe it's because the character design isn't appealing enough or the storylines are not engaging.
There are a few like 'Chubby' from a well-known cartoon series. This character is always getting into adventures and making kids laugh. Another could be 'Lily the Panda Cub' who has a sweet personality and teaches kids about friendship.
Maybe it lost its way or couldn't find its mom. That could make it sad.
Maybe it lost its way or didn't get enough food to be happy.
Maybe it's to evoke emotions or tell a specific story. Sometimes, sad characters add depth and drama to the cartoon.
Baby pandas are cute in cartoons because of their chubby appearance, big eyes, and fluffy fur. Their innocent and playful nature also adds to the charm.
