The differences of creating the rim (wheel) and the bug

The difference of bug and rim (wheel) is:

1). The rim (wheel) was a motion tween inside the movie clip (MC), but the bug was a frame by frame animation

2). The rim (wheel) was created already and the bug we needed to created

3). In the bug animation, had a great number of layouts in our animation

4). The rim (wheel) animation needed to be rotating clock wise (CW), but the bug animation could be anything you wanted to move

5). Wheel animation you need to break apart the rim by doing shift+clicking the parts

6). You needed to create the body parts of the bug
