Descriptions
The level starts off in a jungle-filled section with many Neurons, as well as numerous platforms over large pits. There are also mushrooms in the background of some areas. The Neurons often block routes to other area and spaces containing fruits, and some of them must be moved to proceed. Many Neurons can also be used as helpful platforms to cross significant gaps. Some Neurons move on their own, while others only move when the Yoshis Ground Pound on their heads.

Another section of the level is a watery area where many frogs dwell, with Neurons becoming less common.

A third section of the level is filled with numerous sea cacti.

Storybook segment
''Strange creatures come out at night, and, in the jungle, it was always dark. Neurons lived in this jungle, but they weren’t as wild as they appeared. Instead, the Neurons were quite tame, and they happily helped the Yoshis escape.''
