Peachaisalina

Peachaisalina is the polyship between Peach, Daisy, and Rosalina from the Super Mario fandom.

Canon
Princesses Peach, Daisy, and Rosalina are all female characters featured in the Super Mario series. They are playable characters together in multiple spin-off games. Examples include Mario Party and Mario Tennis. Dialogue from Mario & Sonic reveals that they will occasionally shop together, confirming their status as friends.

Peach and Daisy have known each other the longest. Their first canon interactions stem from Mario Tennis. Ever since then, the princesses have been each other's default partner. Examples of this can be found in Mario Golf: Toadstool Tour and Mario Kart: Double Dash!! They will also refer to each other as 'sister-in-arms,' a term meaning two women who share a close bond with each other.

Rosalina's introduction in Super Mario Galaxy has her help Mario save Princess Peach. As she does so, she only refers to Peach as Mario's "special one." Despite this, the two only interact in Super Mario 3D World, Super Mario Kun ' s retelling of Galaxy, and multiple spin-off games. With their minimal interactions, they are portrayed as allies.

The trio are all playable characters in Super Smash Bros. Ultimate. In Daisy's classic mode, Peach and Rosalina are opponents Daisy must go up against. She also has both a pink and blue alt that represent the latter. Promotional art and commercials will also have them fighting together.

Fanon
The trio are shipped together due to their status as friends. Some fans also feel that the trio are better for each other instead. While not as popular as its other variations, the trio are commonly drawn together in fan art with both romantic and non-romantic contexts. Fan MMD videos may also have the trio dance together.

One noteworthy fanon portrayal of the polyship is in TheBourgyMan's "The 3 Little Princesses." In the webcomic, Peach and Daisy have Rosalina stay over for the night due to her observatory needing repairs. As the night goes on, Rosalina becomes more and more frustrated from the duo's behavior. As it would turn out, they had the tape Rosalina needed earlier, causing her to lash out. They then apologize the next day. Recently, the comic has been revived and focuses on Daisy's stuggles with popularity when compared to the others.

Multiple comic dubs and fan pieces have been made based off the fancomic. Dub Matters' full video, for example, has over 700k views.
