Squishy block

Squishy blocks are movable platforms that appear in Super Mario World 2: Yoshi's Island and its reissue. They are pinkish-orange blocks that move when pushed. When pushed against a wall, they squish against it, growing taller and thinner. When they are ground-pounded, the inverse happens. This is an easy way to transport items over spikes. Squishy blocks are very rare, and they appear in only three levels: Chomp Rock Zone, Sluggy the Unshaven's Fort, and King Bowser's Castle. In the Game Boy Advance reissue, there is a translucent squishy block in Endless World of Yoshis, bringing the total to four.
