Mecha Beast Slugterra Novels & Stories

I can know what most of the upgrade does just from their name except for the Curved claws and Suction skin. [Curved claw: Makes the claw curved to help in climbing walls, to get more grip and impaling] [Suction skin: Form suction cups on the skin to help stick to the surface of any solid and improve stealth] Not what I had in mind but it's okay. The number next to the upgrades must be their cost I think...hmm can I stack two skins at the same? One way to find out. [Do you wish to upgrade to Suction skin and Light skin]
