Eggo-Dil

Eggo-Dils are enemies resembling daisies with a smiley face in Super Mario World 2: Yoshi's Island, its remake, Yoshi's Island DS and Yoshi's New Island. Each Eggo-Dil has five yellow petals which spawn when Yoshi draws near and rotate around the enemy for a while, being launched in different directions afterwards. After dispersing its petals, the Eggo-Dil's head shrinks itself and soon grows back with another set of petals, repeating the attack pattern. The petals of an Eggo-Dil can damage Yoshi, but he can also eat them up to refill his egg supplies. A Ground Pound performed on the same screen as an Eggo-Dil's head is able to shrink and stun the enemy, causing all of its petals to simply fall off. However, the enemy's head will regrow itself as well as its petals soon after. A Chomp Rock can destroy the enemy permanently, as can a Giant Egg, which turns it into a star. The plant's face itself is harmless.

An Eggo-Dil also appears in Tetris Attack, partnered with a Flutter.

 * Shogakukan guide: クルクル回る花びらがクセモノ. 近くでヒップドロップをすれば、花びらを全部落として気絶する. タマゴの補給には便利な敵. (The spinning petals are peculiar. Hip-dropping nearby will cause it to drop all of its petals and faint. A useful enemy for replenishing your supply of eggs.)
 * Player's Guide: These fast growers are indestructible, but their petals provide a full supply of eggs.

 * Shogakukan guide: クルクル回ってから四方に飛び散る花びらはぶつかると痛いが、食べればタマゴにできる. 近くでヒップドロップすると花びらが全部落ちて気絶. (The petals, which spin around and then scatter in all directions, are painful when they hit you, but if you eat them you can turn them into eggs. If you hip-drop near it, all the petals will fall off and it will faint.)
