Well technically, octopus does not come from a Latin origin, so it follows different rules, but other than that, you got everything correct.

Yes, you are correct. The word "octopus" does not have a Latin origin, so the standard Latin plural form "octopi" is technically not accurate. "Octopuses" is considered the more correct plural form. Thank you for pointing that out!
