If you count the hand-held games as part of the canonical series, then "Season of Ice" is the fourth title. If not, then "Enter the Dragonfly" is the fourth.
Spyro
I believe the name of the cheetah on Spyro is Meadow.
Yes in Legend of Spyro her name was Cynder. In Spyro her name was Ember, and there was going to be a Legend of Spyro where Cynder changed her name her new name was going to be "Ember" but that game was canceled due to Skylanders.
Spyro: Enter the Dragonfly
The Legend of Spyro 3-D.
the new spyro game is skylanders spyro's adventure
If you see somebody playing with Spyro, go to the chat thingy and go to where it says "Hi" then find the player playing Spyro's name.
