Red Block

From the Super Mario Wiki

Red Blocks are a varity of blocks found in Mario vs. Donkey Kong 2: March of the Minis. They are the same as Pink Blocks but they have another use. If there's wood and the player picks up red blocks a red glow will be in the backround. When the player touches the screen a fire ball will appear instead of the usual Stars. At this time the player can burn wood once. The player has to keep in mind that if any Mini Marios touching the wood will also be burned. They are mainly seen in the Lava Dome and can be used in the Lava Dome Kit, the Special Kit 2 and the Special Kit 3.
