Tohklor tallow was a Yuuzhan Vong weapon that created a frictionless coating to form on exposed surfaces causing anyone walking through the area to slip and fall down. The weapon was actually a smelly tick-like creature that exploded when it hit a surface spraying its corrosive tallow over anyone and anything it hit.
The creature weighed approximately 1.6 kilograms on average.
