Plant Kingdom

Plant Kingdom is the first zone in Sonic Rush Adventure (excluding the training level). Located on a island, west for Southern Island in the Sol Dimension, this zone features a jungle theme with a green and lust landshape, a common trait among the first levels in the sonic serie.

Overview
Plant Kingdom initially starts on a beach, but the majority of the level is jungle/forest themed, with grind vines and mushrooms. This level bears a resemblance to Mushroom Hill Zone.

Towards the end of Act 1 there's a 3D section were Sonic has to hop on three vines and avoid obstacles.

The boss of the level is Ghost Rex. He'll attack by biting down and by ramming you from the side. When he attacks, jump on his head as many times as possible. When his health is halfway gone, he'll stomp on the ground, breaking it, and you'll fall into a pit. He'll attack similarly, except his bite will be a head-slam, and hitting him is harder. When his health is all gone, hit him once more and he'll explode.
