Cofato scuttle along the ground with their shadowy limbs, but are easily mistaken for an inanimate piece of treasure if they retract them. Cofato that use this to hide will wait until they are picked up to slash with their shadowy claws.
Cofato fossils were traditionally laid to rest alongside ancient kings and queens. This was done due to a belief that their fossils would spontaneously revive to defend the tomb from intruders, but this has since been proven false.
