Eagle

Appearance
If the Eagle's appearance is the same throughout the game's development, the Eagle is a blocky resemblance of it's real-life's counterpart, the eagle.

Speculation
The Eagle has especially unproven speculation based around it compared to the other animals in Cube Creator DX. For attacks, it has a few options, those being pecking or scratching. It is mostly correct that this should fly, as shown in the image above.
