F.L.U.D.D.
From: Super Mario Sunshine (2002)
- High-tech water pump designed by Professor E. Gadd.
- Uses water to clean up graffiti, douse flames, aid mobility, annoy hapless natives, etc.
- Has three interchangeable nozzles (Hover, Rocket and Turbo) along with the standard Squirt Nozzle.
- Offers annoying helpful hints in robotic monotone.
- Is tragically destroyed during the final battle (but gets better in the end).
- Appears as one of Mario's moves in Super Smash Bros. Brawl and its sequel, and as an item in the Mario Kart Arcade GP series.
- Is it possible for a machine... to possess a soul?

Luma
From: Super Mario Galaxy (2007)
- Adorable, chubby star baby.
- Gives Mario the ability to do a Star Spin, which serves as his standard attack and also gives a little extra height to his jump.
- Can apparently turn into a bunny at will, if the game's first mission is any indication.
- Sacrifices itself to stabilize a supermassive black hole and restore the galaxy to it's former state, or rebirth the universe, or whatever the hell happened at the end of SMG.
- Reappears in Super Mario Galaxy 2 with the same function as before, and as Rosalina's partner in Super Smash Bros. U/3DS.
- We are all made of star stuff.

Cappy
From: Super Mario Odyssey (2017)
- Friendly hat-ghost-thing.
- Lets Mario possess "capture" sentient beings. But not if they're wearing a hat, for some reason.
- Can also be used to collect nearby items, and to serve as a platform for Mario to bounce off of.
- Can be controlled by the second player in co-op mode.
- Joins Mario to rescue his sister Tiara, who is also a hat-ghost-thing.
- Can be cosmetically changed into a sombrero, a fedora, a toque blanche, and more!
- Our hats are off to you, Cappy.
