Not a whole lot of people do spider to spider breedings, but if one were to then there is a chance that you could increase the possibility of getting the head wobble. But then again its not really a guarantee, there are alot of variables one must take into account on that.
If a spinner blast was bred to a spider the odds get kinda funky.

6.25% chance of a Normal
18.75% chance of a Spider
6.25% chance of a pin
6.25% chance of a Pastel
18.75% chance of a Spinner
18.75% chance of a bumble Bee
6.25% chance of a Pastel Pin
18.75% chance of a Spinner Blast
Wouldnt you get spiders, spinner, bumblebee, and spinner blast? When you cross two spider genes together you produce 100% spiders right? Which will eliminate the possibility of producing normals, pins, lemon blasts.
