Me and my friend found this out by accident. We were shocked when we realized we killed the dude but my friend was happy for no annoying babies hitting us. I was less skilled and playing as Chalice so my friend told me they wanted me to keep killing him so they could get through the stage faster. :P we were unsure how far we were progressing but surprisingly, it was easier for them to beat the boss.
Thanks for saying that! I don’t have a boo plush but I will get one with my birthday money(in 15 days) and I’ll record bowsers voice and pitch shift it to boos.
Yep, i did knew that, but that just happens when you stay fighting Broly. After a moment, he will thank you and then you have to kill buu so the mission ends
