I've played so much Super Mario Bros on the Wii with my young kids and the bubble mechanic is excellent. We've just started playing SMB Wonder on Switch and one of the changes is that it's no longer a bubble but sort of like a shooting star and you no longer need to manually trigger it. The new Nabbit character is also something that was added in the Wii-U game. This character isn't harmed by enemies, so can just run around only worried about environmental dangers. To balance this out, Nabbit can't pick up any power ups. It's a neat idea that returns again in Wonder, but now with more characters to select from you're not forced to have one of 4 players using it.
