Mucolid Spore Clusters are allowed to assault Zooming Flyers or Swooping Monstrous Flying Creatures.
If they do so successfully then they will explode as described in the Floating Death special rule, hitting the target automatically, with Strength and AP as described above. Hits on Zooming Flyers are always resolved against the target model's side armour.
