Okay, I never actually got a notification for this reply. I don't know what happened, but I'm sorry for the wait. D:
ORDERDAD is one of three bosses where the Bouquet fails, since it's more of a scripted gag (like the rest of the dreams) rather than an actual fight. The other two bosses are Cracky (who disables your accessories at the start), and... a hidden superboss from the main game that I'm not sure if you've found yet. (The one in Bell Cave, have you found it)?
I don't think there are any other ways to farm Bottles of Swag? I remember that I purposely made them rarer and harder to get than the various other stat-raising items, because I didn't want players to becoming too overpowered with them and just one-shotting everything.
And like I said before, please don't be sorry about the questions! It's made me so happy to have someone interested in this. :3
