Stickers - Expanding the range

I''m thinking of including stickers in the pack.

Reasons:

1. It sweetens the deal: a way to draw in children's attention - free prizes.

2. They are body parts so they can make anything into an insect - interactive element

3. It expands my range of products and makes this a more well rounded product

I'll need to re draw these because the sizes of the parts are all random, like the mouth pincers are bigger than a leg. So when I redraw I want to try and get it roughly proportional so that the sticker may be used together on one object.
