Not sure if anyone else has discovered this or not but good lord it was random ... o_O
So I was playing SM63 for the first time in ages and I was fighting bowser in the second battle him and Mario have. I'd already thrown him off the platform and into the fire balls once, and so I went to spin him round and round with his tail. I succeeded. But he fell off the platform without hitting the fire balls until halfway through his fall, and therefore all you see is bowser being thrown into the transition wall over and over and over and it doesn't stop. You actually have to commit suicide as Mario by jumping off the edge to progress further.
If you found that difficult to understand I thought I had a screenshot but it turns I pressed print screen at the split second he disappeared off the screen before being thrown back and forth over and over. So due to bad timing, that's become pretty useless.
