It all makes sense now.

Level 10: all forms are valid as long as enough people use them. The currently most used forms are octopuses and octopi, both valid, but octopi is malformed, so octopuses is preferred. Octopussses and octopii and rare variants of those. Also correct, but rarely used.
Octopodes is also correct, but considered pedantic.

Level 11: Just use what you are used to.

Not boars, tho.
Wolves prefer not to fuck with adult boars.
Even when European lions were still around, they’d rather go for something else over a boar. Even bear cubs or baby mammoths, with all the risks involved.
Without some metal animal like Komodo dragons, it falls to humans to keep them in check.
