Giant Flying Manta

The Manta Ray or Kite are placeholder names given to a large flying creature that roams the world.

Behavior
The Manta glides through the sky, and it is accompanied by swarms of small bird creatures. It seems to patrol in a fixed path. The Manta and its flock are immune to the engineer's attacks. The Engineer can jump onto it and take a ride. Doing so generally requires a or tall Ladder. Take caution as the engineer can only stay on the center part of its body.

It can fly through engineer-made tall structures. Its body emits blue lights during the night. Its current purpose seems to be merely decoration.

Trivia

 * 1) The Manta at the Grass Land takes exactly 5 minutes to make a round trip.
 * 2) If the engineer is building factories in the Manta's path, sometimes the engineer could be taken away by Manta from the foundations, so take note.
