Piranha Grove

Piranha Grove is the jungle found atop Yoshi's Island. As such, its only appearances are in Super Mario World 2: Yoshi's Island and Yoshi's Story.

The Piranha Grove (named World 3 in Yoshi's Island and Page 4 in Yoshi's Story) is the native home for all Piranha Plants (other than Putrid Piranhas and Delfino Piranhas). In Yoshi's Story, stage 4-3 has the name of the jungle, and takes place in the depths of it. The jungle, as told by the game, is ruled by the giant Piranha "Stalks" (these Piranha Plants are the size of a short skyscraper and act very much like trees), and probably was once ruled by the Naval Piranha, the boss of the jungle in Yoshi's Island.

The river of the Piranha Grove is infested with eels, Nep-Enut, Grinder, and Blurps, while the swamp is the only known home of Neurons. The canopy is the home of the elusive relatives to Clubbas, known as Gabon. The inner forest is completely covered with Piranha Plants, and the ground is almost impossible to see. The trees are in a better state, but they too have an uncountable amount of Piranha Plants wrapped around them. The clearings are home to the seedling and juvenile Piranha Plants, known as Piranha Sprouts and Piranha Pests accordingly.

In Yoshi's Story, the four stages in the Piranha Grove are:
 * Jungle Hut
 * Jungle River
 * Piranha Grove
 * Neuron Jungle
