I was Olimar fighting Sonic on Bridge of Eldin when I got a Smash Ball. King Bulblin appeared and destroyed the center of the bridge. Sonic was in the middle when I released End of Day. I spiked him into the pit (he lost a life) but suddenly he was back on the stage still getting mauled by my FS.
I took 2 lives off him without him ever leaving the stage.
