In one episode, he states that he likes to go into the middle of a sandstorm or tornado and stay there meditating, as he calls it the "Zen Zone". In another episode, he states that he submits himself to scientific experiments for money.
The Sims 2 (Nintendo DS) Edit
Tristan builds all the places for the player's hotel. Except for the casino, which he finishes immediately, each room takes 8 hours to complete. When the player first meets him, Tristan is sad because the woman he loved was taken away by a pack of giant scorpions and he claims to catch meteors with his bare hands to cure his loneliness. It is up to the player to console him and convince him to build rooms for the player. He considers working as a carpenter, but states that his job is to test pilot experimental jets.
His secret is that he composed a symphony in his head at age 6 while climbing Mount Everest.
