Big Beanie

"You made it?! HUGE mistake. Say hello to Big Beanie and his unstoppable vines!"

- Kamek

Big Beanie is an enlarged Mame-san that acts as the World 1 boss of Yoshi's New Island. He is planted with Kamek's hammer and turns into a beanstalk leading to the sky with himself at the top.

Appearance
Big Beanie is a giant beanstalk, though Big Beanie himself is a large chili pepper-shaped bean growing on the top of the plant.

Battle
Big Beanie attacks by spitting out Mame-san from his mouth, which can provide Yoshi with some eggs. When he is hit, Big Beanie turns red, raises an indestructible spiked beanstalk in front of him that prevents Yoshi from damaging him in this state, and summons more spiked beanstalks from below that hurt Yoshi upon contact. Eventually, Big Beanie turns green again and the spiked beanstalk retracts back through the clouds and is replaced with a normal beanstalk that shares the same function of protecting him; however, it can be destroyed by eggs, which allows Yoshi to hit him again. Upon turning green after being hit a second time, two normal beanstalks as opposed to just one are raised to protect Big Beanie, and he is defeated if the player repeats this process once more.

Trivia

 * Big Beanie is the only boss to appear in the video game's official artwork, not counting Baby Bowser.
