What's the matter with the goblin returning my grandfather?

The goblin took my grandfather back from the gourd doll. The goblin returning my grandfather is the mantra of the cartoon Huluwa brothers, and later it was played by netizens as a stalk. Huluwa tells the story of seven gourd brothers who changed from a god gourd to a super gourd. Because grandpa was taken away by the magical snake spirit monster, in order to save grandpa, Huluwa went wave after wave and fought against the goblins.
