I have a question

[Saphire]

Is Frankie Munoz hispanic or part hispanic? I'm pretty sure the name "Munoz" is hispanic, but he doesn't look it.

His name isn't Munoz - it's Muniz.
According to the IMDB Frankies ethnic heritage is 1/4 Italian, 1/4 Irish (his mother) and 1/2 Puerto Rican (his father).
