Green Hill Zone is the first Zone of Sonic Blast. It is a tropical Zone with trees, green grass and waterfalls. The enemies are similar to those of Emerald Hill Zone in Sonic 2.
||Sonic (or Knuckles) starts out the adventure in a tropical forest. Hills and valleys abound, and rickety wooden bridges cross treacherous rivers. Watch out for the piranhas and coconut-tossing monkeys!
