Big Beanie's Castle

Big Beanie's Castle is the eighth level of World 1 in Yoshi's New Island and the first castle level of the game. It is home to several Mame-san, one of which gets turned into Big Beanie by Kamek and acts as the level's boss. The level features Countdown Platforms, which can be stepped on a certain number of times before they disappear. It also introduces pairs of large solid blocks with smiley faces on them that slowly revolve around in a set direction and can be used as platforms; blue ones move automatically while orange ones can be activated or deactivated by hitting nearby orange switch blocks.

Overview
Shortly after the starting position, Blue Yoshi has to traverse a series of Countdown Platforms over lava, avoiding Mame-san and Shy Guys. Afterwards, there is a door which leads to an area with the Checkpoint Ring, followed by a series of smiley blocks that move around. Eventually, after climbing two pairs of moving blocks, Blue Yoshi encounters the boss door. Past the door, a series of stairs lead to a Mame-san, which grows into a tall beanstalk after Kamek squashes him with a magic hammer. A boss battle commences as Blue Yoshi climbs to the top of the beanstalk, where Big Beanie awaits.

Big Beanie primarily attacks by spitting Mame-san at the Yoshi. Yoshi can use eggs or the Mame-san against the boss to inflict damage. After each hit, Big Beanie will extend several thorny stalks from the platform Blue Yoshi is on, retracting them shortly afterwards. In the second and third phases of the battle, he protects himself with stalks, which Blue Yoshi can destroy using Mame-san or eggs. After receiving three hits, Big Beanie shrinks down, defeated.

Smiley Flowers

 * Smiley Flower 1: The first Smiley Flower is located behind a locked door at the beginning of the level. The key to this door is held inside a hidden Winged Cloud which overlaps with the first set of three Countdown Platforms that Blue Yoshi encounters. After obtaining the key, the Yoshi can proceed through the door, where he will find the Smiley Flower above several Countdown Platforms.
 * Smiley Flower 2: The second Smiley Flower is located shortly afterwards, inside a hidden Winged Cloud that overlaps with two Countdown Platforms above a red Shy Guy.
 * Smiley Flower 3: The third Smiley Flower is held in yet another hidden Winged Cloud, floating near a row of Countdown Platforms at the left of an Egg Plant. Blue Yoshi can reveal it by throwing an egg at a trail of coins.
 * Smiley Flower 4: The fourth Smiley Flower can be seen at the top right of the first pair of moving blocks past the Checkpoint Ring. However, it cannot be entered from that side due to some opposing Flippers. Blue Yoshi must go down a passage at the bottom and use the next set of moving blocks to reach the passage at the top, which leads to the flower.
 * Smiley Flower 5: The fifth Smiley Flower is held inside a hidden Winged Cloud shortly after the previous area. Blue Yoshi will encounter two pairs of orange moving blocks, the second of which rotates under a small alcove where the Winged Cloud is located.
