A trap I have used to trap a thyla is a I like to call a box trap. All you need is four fence foundations, a large bear trap, and 16 door frames. First put the bear trap down, Then on all sides place a fence foundation then put the door frames on the fence foundations ( two doors high, and remember to leave one side open to lure in the thyla) then let your desire thyla into a trap, and when it gets stuck in the bear trap, close in the side that's open. And then of course knock it out and feed it with its desired food. This trap works well with other creatures as well. I hope this helped- ZXDragno
