Each pet will get a mystery dance move. This dance move is not known until after you’ve saved up the coins (300 coins) and purchased the dance. Once you buy the dance, it will appear as one of the selectable dances.
To purchase a mystery move:
1. Swipe down on your Gabb Watch and select the Gabb Go icon
2. Select the coins icon (top right corner)
3. Select "Actions"
4. Swipe through actions to find the mystery move
5. Tap to purchase
