The Buzzy Beetle (SMB3) is a blue koopa whose shell looks heavy. It is commonly found in underground/cave levels. With the shell's protection, the Buzzy Beetle is immune to Fire Mario and his fireballs. Buzzy Beetles are similar to Koopa Troopas, since you can kick Buzzy Beetles' shells into a pit, or, you can make it collide with a tile to make it bounce back.
