Radadactyl is a Special Agent exclusive to Bloons TD 5 Mobile. It costs 100 to purchase and attacks by swooping around a nest, popping any bloons that it passes over. Every round an egg hatches and one Radadactyl comes out until all 5 eggs have hatched. It cannot pop Lead or Camo Bloons.
The Radadactyl Pro, "Radderdactyls", have bigger wings; they can blow back bloons with each flap and can pop far more regular bloons before going back to their nest.
The Radadactyl is named after the pterodactyls, a genus of relatively small pterosaurs that lived in the Late Jurassic period. The rada- part of the name is possibly derived from the word "rad", meaning "impressive".
This is one of the towers that does not show pop count despite being an offensive tower.
This tower can be immensely helpful on the three times around track.
