Yeah, 3-2 is that level with a bunch of Scrabbits and an old man who levels two of them up.

Just kill all the Scrabbits but one, and keep passing Marona's turn until the Scrabbit is level 9999. When it's there, throw something confinable near it, and confine a character that has the Big Bang skill and you get an instant 100 some levels. Just make sure you have your character's max levels raised a bit.

It's really easy.
