Remember how everyone was crying because there had always been octoroks in every Zelda game up until Twilight Princess? It seems that we might have been wrong...
I'm sure you remember these guys...
They're called MINI FREEZARDS. They slide around like curling stones when you hit them with your sword.
In Spirit Tracks, there are identical enemies called FREEZARDS. They act exactly how they did in
TP.

Anyways, I was just playing
ST, when I melted the ice off of one of them with fire, and an octorok was revealed to be inside of it!
Here is my logic...
Mini-freezard (
TP) = Freezard (
ST) = OCTOROK
