Dream: He was only 5 years old when Puffy found him in a cave, too and later he found George in the forest admiring the flowers
George: He used to live in a chanpiñon so when he grew up he made his house with mushrooms too
Sapnap: Badboyhalo found Sapnap in the nether, near a fortress, and he was haunted by some piglims, so he has a greater resistance to lava than the others
Ranboo: The crown that Ranboo has is the only thing that reminds him that he was important, since he does not remember anything
Tubbo: Tubbo hates alcohol as it brings back very bad memories of when he was a child
Tommy: Tommy's shirt was totally white but after seeing the Technoblade cape he also wanted to put a little red on his clothes.
