It has purple skin with green horns, claws and spikes. Its body is covered in orange pumpkins. It has orange spots on its wings.
Its name comes from the word "gresskar", which is Norwegian for "pumpkin".
It's strange how this dragon uses pumpkins to make its armor due to the fact that pumpkins can't protect it from weapons, both human and dragon wielded. Also, the pumpkins would melt off it when it uses its hot fire.
It is possible that the orange dots on its wings are pieces of pumpkins, though this is unlikely.
