Newbie on ripping Kingdom Hearts 1 and 2 models

Hello everyone. I am kinda new to ripping models from my favorite PlayStation 2 games, Kingdom Hearts 1 and 2, so I require help.

I heard there was a way to do so on YouTube, but it made my head hurt. I'm looking for a much more easier way to get the models of the Bouncywild from Kingdom Hearts 1 and the Fortuneteller Heartless from Kingdom Hearts 2. Any ideas?
