The Mario characters if they had tumblrs:

Mario: Shamelessly reblogs his own selfies, aggressively comments on anything tagged #Olive_Garden, sometimes leaves nice comments on Luigi’s posts. 

Luigi: Black and white photo posts, aesthetic posts, often provides self care tips, a simple and clean theme, has #ghosts blacklisted but checks the posts anyways.

Bowser: Hides his low-key compliments for the Koopalings and Bowser Jr. by ranting about his lackeys. Constantly sends anon hate to Mario but forgets to tick “Ask anonymously”.

Peach: Her layout is all pink and white but is hard to navigate because she made the cursor 4x4 pixels. She posts about cute animal videos and death metal music.

Daisy: Blank layout, only has “DAISY” as the title.

Toad: Reblogs stolen artwork and meme macros that are ridden with jpeg artifacts and watermarks from other sites. A true fuckboy who probably uses the default theme.

Toadette: Runs a soft grunge blog, but only ironically.

Wario: His entire blog is a big corporate advertisement. Tries imitating trending memes, but a few days too late. You can also find updates in regards to his upcoming WarioWare titles, but you might also find a selfie of him and Waluigi.

Waluigi: Posts about sports cars a lot.

Yoshi: Chaotic shitpost overlord. Just posting a text post with the word “Egg” gets millions of notes in a week.
