Relay Heihō

Relay Heihō are bomb-dropping Boo Guys from Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, and Yoshi's New Island. They are found stationed in long rows within the ceilings of certain castles. They relay a single purple bomb, dropping it when a Yoshi approaches them. The Yoshi can perform a Ground Pound to force them to drop the bomb. If they miss, the one who dropped it will hang its head with an ashamed expression, with them starting over a few moments later. However, in Yoshi's New Island, they no longer pause to look ashamed, with a new bomb appearing immediately to be relayed. Due to their position, they cannot be defeated.
