If anyone is going to be enticed into chasing something that makes no sense, it's going to be him. For better or worse. Maybe he's also part cat.

Oh, it took her that long to realize what they're chasing? "It's not glitter!" Is all he manages to get out before he's trying to lunge for the sparkles, almost certain he has the length to catch up and actually catch whatever this is.

Probably doing that around rocks is also a bad idea, but that would require him to think about what he's doing and he's absolutely not about to start doing that. Even if the back of his brain is realizing the danger and his Stand is just quietly manifesting nearby for this inevitable trainwreck.
