I agree with DoubleGJ. We'd better stick to easy funny jokes at the start and then, if we are getting the hang of it, we make something bigger.

Also I think we could perfectly use the queen boss as all she does is screaming and stomping anyway. We just have to say her text lines really 'screamy'. It's hard, but it's certainly possible to use her. But we'll have to adapt the scene to what she does instead of controlling her. And maybe JazzSD may allow us to replace the sprites of one playable character with a non-playable character.
