Level 3 is the most correct.
Not really. Depending on the noun, the plural may be -us (called u-declination) instead of -i (called o-declination)
Example: modus is also modus in plural.
Octopus is a word of Greek origin. Nothing to do with Latin rules.
Octopus is an English word so it is perfectly correct to pluralise it as octopuses. To use octopi is definitely wrong (it's the wrong foreign pluralisation), octopodes is using an uncommon foreign pluralisation so it's not wrong, just non standard

Octopiss
โQuadrilogyโ was such an all-out assault on etymology, semantics and reason that it just made sense when I learned that a CEO came up with it.
Here I was calling the octopussies.
Your prof is Roger Moore?
Confused Squidward noises.
Lv7: the legs [of]* two octopodum got tangled, so the octopodes asked help from two other octopodibus.
ENOUGH OF THE NOMINATIVE TYRANNY!
*it feels weird to use "of" with genitive, it's like saying *"the leg of a cat's".
They have more than 7 reproductive organs?
I actually love octopods. Somehow sounds the least weird of them all.
