@Scanian_dreng platypus is not that weird if you consider that birds evolved from giant lizards. Sacculina is an example of how some species simplified to a point where it's only two actions in life are finding a host and reproduction. Even related barnacles are more complicated than that.
Ability to control crabs despite not having developed nervous system is impressive as well. It is unlikely that it has any further adaptation left to do, except maybe moving to a different species. Serves as a great nightmare fuel too.
