a Stand ability that's purely for transforming into a dinosaur...i can't come with any reason for it aside from the fact that Araki just wanted to draw some dinosaurs
The steel balls may as well be a magic wand at this point. Also the design of the diosaurus changed a whole bunch from the last page of the previous chapter lol
Johnny said the bear must have been alive for it to transform, but that things guts and ribs were hanging out. I'm pretty sure it was dead lol. But its jojo and nobody feels pain so who knows
