While scrolling through Reddit's Nintendo sub-reddit I saw an interesting video that was over on Nintendo's Japanese YouTube channel that shows off Frog Mario in Super Mario Maker...well, sort of. It shows the SMB1 Mario turning into Frog Mario as a Mystery Mushroom costume, so sadly it doesn't have any of the actual Frog Mario functionality, but sprite-wise it looks great including the hopping animation when "walking" and the sprites used when underwater. The stage completion music is also the music from SMB3 for when you clear a fortress or airship. While I'd love to see an actual Frog Mario suit for the Super Mario Bros. 3 stages, this is still pretty nice to see.
