Evil Leafy

Evil Leafy, recommended by MrOrange890, is one of the 30 recommended contestants and the secondary antagonist who could have been voted into the game in The Reveal and Battle For Dream Island Again. She apparently is competing in IDFB.

She is one of the two contestants not participating in Battle for BFDI, though she reappeared in Four Goes Too Far.

BFDI
Leafy's evil "twin" only received 34 votes, placing her 4th in voting and being sent into the Locker of Losers. Evil Leafy lost in voting to Nickel, Bomby and David. Dictionary has described her as a Leafy wannabe. She reappears in Reveal Novum as an icon for the "Staring Contest" text. In Episode 25, Leafy was seen turning into Evil Leafy, but was stopped beforehand.

BFDIA
Evil Leafy got 90 votes to join Battle for Dream Island Again, placing 48th in the voting, which wasn't enough. Evil Leafy is seen in the alternate cut, hiding behind the trees and making four cameos. In Get Digging, she was seen chasing Spongy, Book, and Ice Cube, when she catches up to Spongy, she slowly sinks into him and he is left behind while the other characters escape.

In Insectophobe's Nightmare 3, it is shown that Spongy throws up Evil Leafy, showing that he was not possessed nor captured by Evil Leafy. Soon after, Gelatin comes to freeze her with his syringe and writes "First!!" on her back, ending the episode.

In Zeeky Boogy Doog, Evil Leafy once again sinks into a character, only this time, it was Flower, who was frozen by Gelatin.

In Get in the Van, Flower spits out Evil Leafy. It is possible that she might've eaten Flower. The episode ends with Evil Leafy consuming the FreeSmart Van which was transporting the FreeSmarters, Tennis Ball, Golf Ball, and Rocky, which serves as the plot for the BFDIA 5b game. She stands still for a minute of silence.

In No More Snow!, the FreeSmart team managed to escape Evil Leafy, and killed her by dropping a weight on her, along with Fries and Puffball.

Four copies of Evil Leafy appear at the bottom of the level select screen in BFDIA 5b as an easter egg, and the third one is smiling.

IDFB
Evil Leafy briefly appears in Welcome Back when Tennis Ball grabs the Wall Teleporter, meaning that she isn't dead, possibly recovered.

Book
In Reveal Novum, 's definition of says:

"Evil Leafy - Leafy wannabe. What a loser."

In Get Digging, Pencil warns the Puffball riders to watch out for a wild Leafy, which may have been referring to Evil Leafy. Later, Book, Ice Cube, and Spongy must flee from Evil Leafy but Spongy died.

In No More Snow!, Book and Ruby escape Evil Leafy but then immediately have to run away from her. Book cuts the rope, crushing Evil Leafy, Puffball, and Fries.
