This post needs information about either a time when Private Thorsen leaves for patrol, or notes what event triggers his patrol.

He left for me at 19:58. Users on Thottbot report times all across the spectrum, so it seems unlikely that he has a set hourly spawning time. However one user reported him leaving exactly 2 hours apart, which might suggest that the time between his patrols is indeed 1 hour and only offset by him being rescued or not (whichever may take longer).

Jungle Fever isn't available otherwise.
