Random encounter for Tonberry Doll not appearing

Hello, as the title states I cannot get the random encounter in the Punchinello room to trigger for the Tonberry Doll. Do I have to fight a certain boss first? I'd appreciate any knowledge on this, thx mates

EDIT: I've tried speeding the game up in my emulator but it still never shows up, I'm sure I've put enough time into looking for it by now. I've tried the rooms next to the Punchinello room as well, no luck so far.

In v9, you need to beat Smithy before most post-game bosses appear.

thaank you! I figured it was something like that.
