Hariet

"Lookin' for the Wedding Ring, chumps? Too bad! The Boss has it now! And you guys ain't invited to the wedding!"

- Harriet

Harriet is one of the Broodals, a group of evil, rabbit-like wedding planners appearing in Super Mario Odyssey, which are hired by Bowser to plan the wedding between Peach and himself. Harriet is found atop the Inverted Pyramid in the Sand Kingdom in the mission "Inverted Pyramid Showdown", which can only be accessed after the Moon Shards in the Moe-Eye Habitat are collected to complete "Moon Shards in the Sand". When Mario reaches the pyramid's top where Bowser's Airship with Peach on board hovers, a cutscene starts to play, which shows the Broodals's Airship approaching. Harriet says a few words revealing that Bowser has already retrieved the Wedding Ring before Mario and Cappy arrived as well as tauntingly telling them that they aren't invited to the ceremony, puts a helmet on and jumps off the Airship, attempting to fight the player.

In the fight, Harriet throws bombs at Mario using her braid, which he has to knock back by hitting them with Cappy. After a while, if Mario didn't knock back any bomb, she throws a much larger bomb which is attached to her hair and gets stuck in the ground, so that it can be thrown back easier. When Harriet gets hit by a bomb, she loses her protective helmet, allowing Mario to jump onto her head to score a hit. Then she puts on a new helmet, withdraws her body into it and starts flying around as an UFO while dropping numerous bombs onto the battlefield. After a while or when she gets hit by a bomb Mario threw back using Cappy, she stops her rampage, emerges from the helmet and starts throwing bombs using her hair again. By knocking back one to remove her helmet and jumping onto her head, Mario scores the next hit. After each hit she drops ten coins; and after the third hit, she is defeated, disappears in a cloud of smoke and leaves behind a Multi Moon which adds three Power Moons to the player's total.

Harriet, Pyrotechnics

It's best not to get her mad.

''The least predictable of the Broodals, Harriet is most often found throwing bombs with her hair. When her homemade bombs explode, they leave a pool of fire on the ground, so try knocking them away before they explode. While it may seem reckless to have filled her hat with bombs, Harriet is devious and keeps a lot of spare explosives with her, so watch out!''
