Krendel was a sizable creature resembling a lizard. The reptile possessed shiny yellow skin adorned with a pattern of bright blue and green splotches extending along its spine. Its features included sizable, bulging black eyes and pliable, adhesive pads on its feet, facilitating climbing on steep rock faces. For offensive purposes, it was equipped with pointed, needle-like teeth and the capability to exhale corrosive gas. Krendels originated and matured within the poisonous seas of Recopia, subsequently evolving lungs and extremities. These evolutionary adaptations allowed them to move onto land to hunt for sustenance, typically seabirds that nested in the island's cliffs. Lacking acute vision, Krendel relied mainly on smell and movement to locate its prey. They typically hunted as couples.
