Holon Jungle is one of the seven biomes that make up Holon, each of which holds quite a number of Delta Pokemon. Heavily covered jungle trees makes this area harder to navigate than the usual biome.
Point of Interest
Delta Foongus
Head directly east and a little south of the entrance and you will find a large opening filled with normal Foongus. However, has you get closer, they all run into jungle. However, as hinted by the female scientist located northeast this clearing, one of the Foongus did not leave the area but just blended into the background. Walking around the clearing until you run into something you very faintly see and press enter. The Delta Foongus will jump out of the shadow and will battle you.
Delta Darumaka
Starting from the clearing with Delta Foongus head east until you past a row of normal trees right by Pokéfan Nikola (Balding man). Start heading southeast until you can see a nest ball then head straight down. A tree that looks very similar to the ones in Vipik Gym should be visible and you should be able to climb into it. After going to through the tunnel, head northeast and you should see the Delta Darumaka.
