When you take the Attack action with a Whip and target a creature no more than ONE size larger, you may choose to make it one of three Special Weapon Attacks. This attack is subject to the target's STR save. If you succeed, instead of doing damage, your attack has a special effect.

Whip Snatch: The target is disarmed of one object it is holding, and the object falls within 5 ft. of the target. IF you roll a critical strike the object is brought to you instead. You may catch it from the air or allow it to drop next to you.

Whip Snare: The target is pulled 5 ft. in your direction. IF you roll a critical strike, the target creature is also Grappled.

Whip Trip: The target is knocked prone. IF you roll a critical strike, the target takes 1d6 bludgeoning damage from its impact with the ground.
