Trivia

 * This episode takes place in Arco Iris and the Mushroom Kingdom; and the Koopa Kingdom.
 * The Star Teens are now in their Star Teens outfits throughout the episode, and while their face masks are mostly pulled down under their chins, they are raised to cover their faces, notably against volcanic smog.
 * Peach and Mario switch roles during the second half of the episode. While the Princess ends up escaping Bowser's clutches, Mario ends up being kidnapped (just like they did in Nintendo Power's comic miniseries "Super Mario Adventures").
 * Speaking of which, Peach and Luigi switch outfits during the episode, with him wearing a golden wig resembling Peach's hair; he wears a pink surgical mask to hide his moustache.
 * Power-ups used by Mario, Luigi, Blue Toad, Yellow Toad, and Princess Peach (and later the Star Teens) included the following:
 * Super Leaf
 * Fire Flower
 * Ice Flower
 * Mini Mushroom
 * Mega Mushroom
 * Penguin Suit
 * Propeller Mushroom
 * Super Acorn
 * Super Star
