Doodeng!

Het is Halloween. Wat eng. Die enge Fisherman achtervolgt me! Hij loopt me achterna!
(It´s Halloween. How scary. That scary Fisherman is chasing me! He is running after me!)

Both "Achtervolgen" (achter_volgen) and "achternalopen" (achterna_lopen) are composed verbs. However "achtervolgen" is not separated!
