Gohan, Krilin, Bulla and Olong are spending a peaceful day camp, but that night, a major fire took off in the nearby forest. Krilene and Gohan used their strength to extinguish the fire and rescue the animals. The next day, the group detects dragon balls using dragon radar, and calls Onnon to restore the forest. Later, Gohn befriended a purple dragon, named Icarus (Higher Dragon in Japanese), which he and Krilin saved from the destruction of the forest by fire. According to the group, the discovery of the fire was initiated by a space probe, sent by a cyan named Turence, who has chosen earth to plant the tree, a mysterious, powerful tree that absorbs the energy of the world Stores it in its fruits, and whoever eats it is given godly power.
