For a horror story on thalassophobia, think about using sensory details to make the reader feel the cold, salty water and the oppressive vastness of the sea. Have the main character face escalating threats from the ocean, like sudden strong currents or creepy sea plants that seem to have a life of their own.
I don't think there's an obvious connection. Each term has its own distinct meaning and context. 'Caricatura' is for humorous or exaggerated drawing. 'Matador' is in the realm of bullfighting. 'Tutela' is more about safeguarding or looking after. They seem quite separate.
Well, it might be that something influences the style or theme of the cat cartoon. Or perhaps something is a product based on the cat cartoon. Hard to say for sure without more context.
