animated intro
This is a fun toy that displays a unique crawling action when rolled or pushed across a surface. There are lots of little parts to deal with, and therefore it is more challenging to make than it may look. In the end, however, its a great toy that is as fun to make as it is to play with. As we do with most of our plans, we leave plenty of room for customization so your bug can reflect your tastes.
