Crazee Dayzee

"This is a Crazee Dayzee. Crazee Dayzees look cute, but you won't think they're so cute after they attack you!"

- Goombario

Crazee Dayzees are flower-like enemies that made their debut in Super Mario World 2: Yoshi's Island. They later appeared in the Paper Mario series, Yoshi's Island DS and Yoshi's New Island.

Super Mario World 2: Yoshi's Island
Crazee Dayzees' first appearance is in Super Mario World 2: Yoshi's Island, where they act as minor recurring enemies throughout the game and can have either white or yellow petals. Crazee Dayzees behave identically to Shy-Guys in terms of behavior—however, they can survive being swallowed and spat out, unless they collide with another enemy. An uncommon variation with purple petals that spits out bubbles known as Bubble Dayzee can also be found in some levels.

Yoshi's Island DS
Crazee Dayzees reappear in Yoshi's Island DS, where they act as they did in the previous game. They are found in many levels throughout the game, including Ba-dum BUM!, Hit the M Blocks!, Mario's Fleet Feet, Baby Mario and Baby Peach: Dynamic Duo and Donuts and Eggs. Notably, the Bubble Dayzees do not appear in this game.

Yoshi's New Island
Crazee Dayzees reappear in Yoshi's New Island and act as the same as they did in the previous installments of the Yoshi franchise.

Paper Mario series
Crazee Dayzees in the  Paper Mario series all have lavender petals and purple feet, potentially inspired by Bubble Dayzee's design.

Paper Mario
Crazee Dayzees make their first appearance outside of the Yoshi series in Paper Mario, where they first appear as enemies in Flower Fields. They attack Mario on sight and often fight alongside Bzzaps! and Ruff Puffs. They typically attack by singing, putting Mario to sleep. They will flee from battle when Mario gets their HP low enough. A rare variant known as the Amazy Dayzee first appears in this game, which has higher HP, and much higher attack in comparison.

Paper Mario: The Thousand-Year Door
Crazee Dayzees, along with Amazy Dayzees, make a return appearance in Paper Mario: The Thousand-Year Door. In this game, they can be found along the Twilight Trail near Twilight Town. Like in the previous installment, they attack by singing, putting Mario or his partner to sleep (while also piercing defense), and flee from battle at low HP. Amazy Dayzees also appear in the lower levels of the Pit of 100 Trials and alongside other enemies in Twilight Trail. Starting with Twilight Trail, Crazee Dayzees can start appearing in the audience; if one sings, it will put a large swath of audience members to sleep for a short period. A Crazee Dayzee with green petals and blue feet, known as Hayzee, appears as Luigi's ally. He joined Luigi on his adventure to assemble the Marvelous Compass after being impressed by Luigi's portrayal of "grass" in a play. Hayzee is from a town of Crazee Dayzees known as Jazzafrazz Town, which is the first time that a Crazee Dayzee is shown to be an ally, rather than just a simple enemy.

Super Paper Mario
Crazee Dayzees return in Super Paper Mario. They can be found in the Dotwood Tree and room 26 and 58 of the Flipside Pit of 100 Trials. When they sing, a musical note fires from them towards the player like a projectile and puts them to sleep when hit. Its stronger variety, the Amazy Dayzee, also returns.

Super Smash Bros. Ultimate
A Crazee Dayzee appears as a spirit in Super Smash Bros. Ultimate.

Cameo appearances
In the Super Mario Mash-up for Minecraft, Cornflowers are replaced by Crazee Dayzees.

Super Mario World 2: Yoshi's Island

 * Shogakukan guide: 白と黄色のパソジーさんは、口笛を吹きながらスキップをしているだけ. 紫のパソジーさんは、シャボン玉を吹いている. これに当たるとはじかれるが、食べればシャボン玉を吹けるようになる. (The white and yellow Crazee Dayzees whistle as they merely skip along. The purple Crazee Dayzees blow soap bubbles. These cause bouncing when hit, but eating them will allow soap bubbles to be blown.)
 * Player's Guide: This space cadet likes to hum "If you're going to Yoshi's Island, wear some flowers in your hair."

Yoshi's Island: Super Mario Advance 3

 * Shogakukan guide: とのものは、をふきながらスキップしているだけ. のパンジーさんがふくシャボンをべると、ジャボンがふける. (The white and yellow ones whistle and just skip along. The purple Crazee Dayzees blow soap bubbles which if eaten, allow soap bubbles to be blown.)

Yoshi's New Island

 * Shogakukan guide: 花のような敵で、ゆっくりと地上を歩く. 中には、泡を吐き出してくるものもいる. 正面から泡に触れると後方に押し戻されるが、ダメージは受けない. (They are flower-like enemies, and they walk slowly on the ground. Some of them spit out bubbles. If you touch the bubbles from the front, you will be pushed backward, but you will not be damaged.)

Trivia

 * In the NTSC-U version of Paper Mario, one of Koopa Koot's responses to favors that Mario has completed for him erroneously refers to Crazee Dayzees as "Crazy Dayzees". This error was fixed in the PAL version.
