Mario & Luigi: Superstar Saga
November 17, 2003
In the Starbeans Café, Professor E. Gadd from Luigi's Mansion gives one of his inventions to Mario and Luigi everytime they mix a new coffee, for a total of seven different coffees. Originally, every item obtained was given to Mario and Luigi by a different cameo character (Wario, Fox McCloud, a biker from Excitebike, Link, Samus Aran, Captain Olimar and Professor E. Gadd) but in the end they only retained Professor E. Gadd. Olimar's item was originally going to be the UV Lamp, but it was replaced with the unrelated Cobalt Necktie, removing any reference to the Pikmin series.
Before being scrapped, sprites and dialogues for these characters were actually included in the game, and are still present in its code, but unused. Olimar's dialogue is:
- ...I detect a strange, yet pleasing aroma drifting through the atmosphere of this cafe.
It would seem to require further investigation...
- Wow! This is a rare treat!
If it isn't Captain Olimar!
- What is this? Before my eyes stands a strange life form.
It resembles me slightly, so I shall dub it... Marlio!
...Further investigation indicates that the drink that this Marlio holds is the source of the aroma.
I shall now partake of its flavor.
Why! Its flavor is most satisfying!
Finding that such a drink could be partook of in such a place is a tremendous discovery, indeed!
This Marlio creature exhibits what seems to be a longing expression...
Perhaps it will react if I present it with something...
I have just noticed a strange, unsightly green creature standing next to the Marlio...
It could be a dangerous life form.
I feel I should attack it before it attacks me.
Olimar's statements clearly reference his name being based on Mario's.

Simirlaly to how Olimar is based on Mario, his partner Captain Louie is based on Luigi.
Additionally, some items in Pikmin 2 reference the Mario series. Precisely:
- The "Unspeakable Wonder" is actually Princess Peach's crown.
- The "Flame of Tomorrow", that's actually a box of matches, features an image of Bowser's face on top and the writing "Bowser Breath Brand". On one side of the box there's the writing "TEL 555-TROOPAS".
- The "Decorative Goo", that's actually a tube of blue paint, features the writing "Mario Paint Blue", referencing the game Mario Paint.
- The "Master's Instrument", that's actually a pink pastel stick, features the writing "Mario Paints", once again referencing the game Mario Paint, and it also reads "Peach Pink" referencing Princess Peach.

Super Mario Maker
September 10, 2015
Two of the unlockable costumes that Mario can wear in the game by using a Mystery Mushroom are based on characters from the Pikmin series, specifically:
- Olimar: an 8bit version of his recurring design, when worn it replaces the sound effects with sounds from the Pikmin series. It can be unlocked in the 100 Mario Challenge mode or alternatively by using the Olimar amiibo from the Super Smash Bros. series.
- Pikmin: a yellow Pikmin, a blue Pikmin, and a red Pikmin moving together, when worn it replaces the sound effects with Pikmin voices.
Copyrights for both series are held by Nintendo.
