Vampdash

Vampdash is a Spark that appears in Mario + Rabbids Sparks of Hope. It is purple, has a green tongue, and rides a purple leaf that resembles a bat. It shares its name with one of Rabbid Luigi's abilities in Mario + Rabbids Kingdom Battle. Its ability allows the Hero's dash to inflict the Lifesteal Super Effect, which steals the enemy's health.
