Earth's Ultimate Deciding Battle

Oolong, Kuririn, Buruma, and young Gohan are on a camping trip, when a spy satellite crashes into the forest and starts a raging fire. Kuririn and Gohan battle to put out the blaze, then gather the Dragon Balls to wish for the forest to be restored. One of the animals they save is a Haiyaa Dragon (Higher Dragon) that follows Gohan home to become his pet. The two of them (and Gokuu) play together and have a lot of fun, but Chi Chi wants the dragon sent back to its mountain so it'll stop disrupting Gohan's studies. Meanwhile, a Saiya-jin fighter, Taurus, and his minions are scouting Earth to locate Kakarot. Taurus wants Kakarot and/or Gohan to join him to go domain planets. The minions plant a seed for an energy-eating tree near the restored forest. Taurus plans on eating the fruit of the tree to get a "power up." The tree grows quickly and threatens to destroy Earth. Kaiou-sama alerts Gokuu to the danger, and everyone (Chi Chi prevents Gohan from joining in, but Haiyaa Dragon kidnaps the boy to take him to the battle) goes to fight Taurus. Piccolo joins in to save Gohan, but the demon still plans on killing Gokuu later on. Gokuu denies his Saiya-jin heritage, claiming that he's happy to have been hit on the head as a child, rather than growing up to be like Taurus. There's a major battle, and Gokuu uses a Genki Dama to kill Taurus and destroy the tree. Afterwards, the Genki Dama breaks up, and the lifeforce energy repairs the damage from the tree.
