Vampdash

Vampdash is a Spark that appears in Mario + Rabbids Sparks of Hope. It is purple, and rides a purple leaf. Its Power is similar to the Vamp status effect from Mario + Rabbids Kingdom Battle: When the player damages an enemy afflicted with this status, a portion of the damage the enemy takes is transformed into healing energy, which restores the player's health.
