Itsunomanika Heihō

Itsunomanika Heihō is a rare type of Shy Guy appearing in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, Yoshi's Island DS, and Yoshi's New Island. Itsunomanika Heihō appears as a normal Shy Guy and hides behind foreground objects, such as crystals; if a Yoshi runs through the hiding spot, a Bandit will appear and run off with Baby Mario, leaving the Itsunomanika Heihō in his place. This does not affect Yoshi himself in any way, and the Shy Guy can be knocked off and then defeated with any attack. In Yoshi's Island, it is a green Shy Guy, while in Yoshi's Island DS and Yoshi's New Island, it is red.

Super Mario World 2: Yoshi's Island
Shogakukan guide: ボロドーとセットで、物陰に隠れている. そばを通ると、いつのまにか赤ちゃんと入れかわって、背中に乗ってしまうふとどき者. (He hides in the shadows with a set of Bandits. Whenever you pass by them, they somehow switch places with the baby and climb on your back.)

Yoshi's Island: Super Mario Advance 3
Shogakukan guide: ボロドーといっしよにかくれていて、そばを通るといつのまにか背中の赤ちゃんとすりかわる. 赤ちゃんを取り返せば背中から降りる. (It hides with Bandit, and when you pass by it, it will swap places with the baby on its back before you know it. If you get the baby back, he will get off your back.)

Yoshi's New Island
Shogakukan guide: 木陰に隱れたボロドーとすれ違うと、べビイマリオがこの敵とすりかえられる. べビイマリオを救出すると敵はヨッシーから転げ落ち、このときだけは食べられる. (If you pass a Bandit hidden in the shade of a tree, Baby Mario will be replaced by this enemy. When Baby Mario is rescued, the enemy falls off Yoshi, only to be eaten at this time.)
