In Bottomsup Bay, in one room on the pirate ship, there is a chest containing a Team Skill book. If you grab it, you will see that every one of your vivosaurs has a red move, that may or may not be unavailable in battle. These red moves are team skills. To be able to use them, make a team of vivosaurs that either is the same type or has the same diet (e.g. carnivore, herbivore, etc.). The type is visible in the VMM and the menu, and the diet is visible in the Fossil Museum or on the computer in your hotel room or by the dock.
