Zapsters are yellow slugs found in Mysseru. They are called zapsters because they can produce electricity from their eye stalks to zap predators with. On top of this, they also have an electric slime coating their bodies that prevents them from being picked up without electrocuting whatever grabs at them unless that thing is immune to electric shocks. Zapsters generally stay on trees for most of their lives and eat the leaves that grow on them. They will occasionally come to the ground to move to another tree if their tree runs out of leaves to eat.
