How do I rip Wario World models?

I've been wanting the answer to this question for years now with nothing really popping up. This game uses a compression method in the game's files that I don't know how to decompress and extract. I noticed recently out of the blue new models were approved on the models resource of some of the bosses and enemies all from the user BigBellies, and am wondering how he ripped the models too.

I heard you can rip any Gamecube or Wii models from something like Ninja Ripper and 3D Ripper DX, but those kind of programs never worked for me at all.
