The phrase "Toto was a pretty monkey" suggests that Toto, presumably a monkey, was considered "pretty." In this context, "pretty" typically means visually attractive or pleasing to look at.

In what sense is Toto "pretty"?

• Physical Appearance: Toto might have had features that are aesthetically pleasing, such as bright eyes, a shiny coat of fur, symmetrical facial features, or a charming expression.
• Personality or Behavior: Sometimes "pretty" can be used metaphorically to describe something endearing or delightful in character, so Toto might have had a sweet or appealing demeanor.
• Cultural or Artistic Context: If Toto is from a story, cartoon, or artwork, "pretty" could refer to how the character is designed or portrayed to look attractive or cute.

If you provide more context about Toto-such as the source (a book, movie, or real-life animal)-I can give a more detailed explanation!
