Behind the scenesEdit
Arnold appears only in the "Fists path" of the game Indiana Jones and the Fate of Atlantis where he poses as the hardest adversary for Indiana Jones to encounter. After Anton is killed by a falling stalactite, Jones hears a false yodel and can attempt to roll a boulder at the singer, Arnold, but it goes the wrong way. When they meet face to face, Arnold tells Indy that he wont hurt him if he knows a good drinking tune. If Arnold allows Indy to leave, players can take the stalactite from Anton and try to roll the boulder again in the right direction which smashes Arnold. His body carried an amber fish on a string which later helps Jones find Sophia Hapgood.
If Arnold kills Indy, it is mentioned that he later becomes a world-famous opera singer.
