I've asked about this before on Reddit and Gamefaqs but never really got a response, so I'd figure I'd try here.
I've noticed that sometimes, when I play on Yoshi's Island (Melee), I notice that the giant Bullet Bill in the background randomly flashes on-screen at times, even when it isn't doing its usual background animation. I've tried to see if this has been documented anywhere online and couldn't find anything and was wondering if anyone else has experienced this. I noticed this happen on both the omega and battlefield versions of the stage, but I couldn't really tell with the normal version.
To clarify what I mean by "flashes on-screen", sometimes the Bullet Bill will just appear in the background for a split second before disappearing. I've noticed this happening since Hero came out, and it still happens in the latest patch with Sephiroth.
Again, I haven't seen this mentioned anywhere else online, other than me asking about it, so I wanted to see if anyone else ever noticed this happening.
