The Polero is a red and blue metal element Slug with a white stomach. After hitting 100 mph they split in two, with a tripwire-like appendage strung between the two halves, connecting them. Their usual purpose is to bind an enemy dueler, usually around the legs, and trip them. It is also a favourite of Trixie.
