Buruuba grew bigger in both height and weight, swung more often and was frequently knuckle walking alone. His voice also got deeper and gruffer. By the time he reached 17 years old, he unexpectedly visited the newly decrepit house where he and his parents once lived and decided to dust it with difficulty. He read his parents' nature books in his first language, English, and referred to them when he wrote bits of his teenage diary, but his speech was still fairly stilted and awkward.
Meanwhile, a week later, his adoptive yeti parents died of various diseases transmitted via ignorant weirdos, which traumatised him dearly, but it was also at that time when he finally had learnt that (nonhuman) apes and humans share many similarities in common. Because of this, he finally had to study tropical ecology for the first time in his life.
