Neuron Jungle

Neuron Jungle is level 4-4 in Yoshi's Story. It is the only known place to have Frogs, Neurons, and Ick Worms. These are all nocturnal creatures, but since it's always dark in the jungle they thrive all the time. The background music is "Jungle Fever", the same one as in 4-2, Jungle Puddle. This is the only other given name to the Jungle than the Piranha Grove.
