FALLACIOUS plural form of 'penis'
"Hey, remember that guy that thought 'penii' was an actual word?"
A word made up by people uneducated in the ways of etymology. NOT THE PLURAL OF PENIS.
The rule with aplural form with an I is derived from latin and is only applicable when the word ends in -US, and has no relevance whatsoever when the word ends in -IS.
When a word ends in -IS, the correct plural form is, in fact, -ISES.
(US-I)

The Hippopotamus was huge.
