[TOMT][ANIMATION] An animation about a father trying to fix a lighthouse/beacon

I just saw this on TV, on a channel called Canal Once in Culiacán, Sinaloa around 4:30 PM.

I started watching a movie/short film/animation where there was a father with his son and daughter (named Matías and Lucía, respectively). The son looked young and couldn’t talk, and the daughter looked like a teenager.

They were in a place that looked destroyed or kind of post-apocalyptic. The father was scavenging for things and putting everything in a shopping cart. The son was playing with an astronaut helmet that had a flashlight. He found a battery and put it into the flashlight, but then he did something that annoyed the father, so the father took the battery away.

In the next scene, they went to a lighthouse/beacon where the father was trying to fix it. The son and daughter went to their bed, but the son went back to take the battery again and annoyed the father once more. The father pushed the son out of his way, which caused the shopping cart to fall onto their home, destroying everything.

Here’s where things got wild: the father didn’t notice the destruction of their home and managed to get the beacon working. While this was happening, both of his children moved away from him. Once the beacon was working, a lot of colorful flying fish with glowing lights appeared around it.

The film ended when a whale-looking creature ate the father and took him away, leaving his children behind on the post-apocalyptic Earth.

Does anyone know the name of this fever dream?
