To do so you'll want to jump in the right direction and then press the jump button again and you'll start gliding. At the top you'll be told to glide over the thorns below.
Like the other versions of A New Beginning, gems are no longer collectable. Jump onto and off again the thorny ground to the right. Jump over another gap and then Sparx'll inform you of the dangers of walking over thorny ground. Well, falling in will just pop you back to where you jumped from with a bit of life lost so if you've nearly dead you'll die. This jump doesn't have a safety net so you have to get over it first time. Jump onto the floating platform on the right, and keep jumping until he pipes up again. Move to the right until he starts yapping about jumping. Sparx will inform you of how to control Spyro around.
