What is the necessary background knowledge for watching the cartoon "Huluwa"?

The gourd brothers turned into seven peaks and killed the basilisk and scorpion monster. Green snake was very angry when she learned that her sister had died, and vowed to avenge her sister. The green snake came to the foot of the Seven Color Peak and turned it into an axe with hidden treasures. She wants to dig up the seven brothers one by one.

The green snake first locked the big baby with the array of "Thousand Child Gods", and then blinded the second baby with the salon. Green snake conjured a little shoe and put it on Sanwa's foot. Sanwa couldn't move at once, and Green Snake Essence then took the opportunity to knock him out. She turned into dirty water again, and Shuiwa passed out with a stomachache after drinking the dirty water.

Finally, she tricked Huowa into the ice room, covered Liuwa with gold cymbals, broke Qiwa's gourd and pushed him off the cliff. The green snake threw all the seven brothers of the gourd into the blast furnace, trying to refine the elixir. As a result, the seven brothers merged into "King Kong Huluwa!" Gourd King Kong is very brave. He will break any weapon that Green Snake changes.

The green snake couldn't beat King Kong at first sight, so she had to lure him with a small butterfly. The kind little Jin was soon stunned by the smell of the little butterfly. So the green snake put Xiao Jingang and Xiao Die in the dungeon. When the monster stabbed Xiao Jingang with a spear, Xiao Jingang caught it, but the spear tip broke and Fluttershy was stabbed to death. Xiaojin was so angry that he defeated another demon with lightning, but the green snake ran away. Finally, Little King Kong found the green snake and turned it into a giant gourd. The gourd cracked and seven gourd dolls came out. Everybody, Qi Xin, work together to deal with the green snake essence. Finally, Xiaojingang turned into a mountain peak and trampled the green snake essence to death, and the town was below.
