Jackhammer Yoshi

A Yoshi Jackhammer is a form the Yoshis can transform into in Yoshi's New Island by entering a door with a jackhammer sign on it.

In this form, the Yoshi can break through rocks, however some of them take less time to break but some take more, often resulting in a set pattern of rocks the Yoshi needs to break. Like in every form in this game, Yoshi only has a limited amount of time to use his form but clocks scattered about the obstacle course can provide the player with more time to use the power-up. Going through a ring will cost Yoshi the power-up but will allow him to appear in another area.
