Grab Block

Grab Blocks, also referred to as Blue Blocks, are dark-blue blocks resembling Rotating Blocks appearing in Super Mario World. As their name implies, Grab Blocks can be picked up and carried around by the player, similar to Super Mario Bros. 3's White Blocks. Once grabbed, a Grab Block can be kicked away to defeat enemies or reach distant Prize Blocks. When Mario or Luigi holds a Grab Block, it starts to flash different colors, disappearing after a few seconds. However, a minor glitch occurs if the player takes a Grab Block through a pipe, which causes it to last indefinitely. Yoshi can also eat Grab Blocks, though only after they have already been picked up, and he simply swallows them instead of being able to spit them back out.
