Toadette appears in this blooper as Toad's love interest. Throughout the majority of the blooper, Toad tries desperately to win Toadette's affections, but fails due to various interferences. She has a creepy and weird friend named Frankie who often interrupts and annoys Toad during his time to impress her. Unfortunately Toadette reveals herself to be 9 years old to Toad and she was not interested with the whole love thing, causing a Policeman to appear out of nowhere and send Toad to jail for being a pervert to a young girl.
There is actually shown to be two Toadettes in this video, the first one is seen playing with Frankie until Mario and Sonic kill him by moving the slide to the edge of a building and Sonic turns the spinning equipment into a helicopter that goes all the way to space. The second Toadette is seen having a date with Toad until Toads says he needs to go to the bathroom, Mario gets out a Toad figurine and an Anime figurine to make it look like Toad is cheating and when the real Toad gets back, Toadette shoots him with a tank. The first Toadette is seen again when Waluigi's elevator gets sent flying into space when it opens you can see her on the spinny thing in the background. The first one is seen again near the end still on the spinny thing in space saying "Somebody kill me".
Toadette returns in MARIO'S CHALLENGE, she is shown on Floor 5 as the first contestant of the challenge where you need to jump from mushroom to mushroom to avoid falling in the lava. One of the mushrooms she stands on springs her into the air crushing her on the ceiling of the rock cavern.
Despite saying she hates love in her first appearance, she's been shown dating either Toad or Frankie.
Her personality tends to change from child-ish to grown-up inbetween episodes.
There is debate as to whether or not Toadette is Toad's sister, friend, or love interest, as in Captain Toad: Treasure Tracker, she is stated to be his friend, but other sources claim her to be his sister or love interest.
On the real Mario videogames we can't tell if Toadette is 9 years old or even older.
