Soft rock

Soft rocks are blocks that appear in the Yoshi's Island series. They first appeared in Super Mario World 2: Yoshi's Island and returned in its remake, Yoshi's Island: Super Mario Advance 3, as well as in Yoshi's Island DS. They are composed of thinly packed rocks that can appear in various different color schemes depending on where they are found, most typically either yellow or light gray. Soft rocks automatically merge with other soft rocks adjacent to them, visually appearing as a single mass that reshapes itself as individual blocks are broken.

Soft rocks can be broken using almost any attack, including jumping into them from below (similar to Brick Blocks in the Super Mario series) or spitting seeds using a green watermelon, which breaks them one at a time, or by Ground Pounding them from above or throwing eggs at them, which can destroy large amounts of soft rock at once as the Ground Pounding Yoshi or egg will pierce through the soft rocks as it travels. Chomp Rocks also break soft rocks in front of and underneath them as they roll. Some enemies are capable or destroying soft rocks as well, most notably Chomp Sharks, which tear through large amounts of soft rock as they chase Yoshi, but also Lakitus' Spiny Eggs and bombs dropped by Item Balloons and similar sources. These enemies are typically encountered in areas where the ground is mostly made up of soft rocks, making traversal dangerous for Yoshi.
