Gremlins were first spotted by human pilots during World War II.

These are highly inquisitive creatures who love to dismantle machinery and mechanical devices to see how they work. But they're not so good at re-mantling after. So you see the problem.

Gremlins are native to certain remote tropical islands (where there is very little machinery to get them in trouble). They are easily lulled to sleep by the soothing sound of the music of their homeland.
