A long thin cloud in the form of a straight segment then a sharp 90 degree corner into an approximately quarter circle. Imagine a capital P but with the bottom half of the loop missing. Or a katakana Fu.

Long thin cloud made of a short straight segment, a 70 degree corner, 1/2 a circle back towards the straight part, then a flick back away. Like a capital R made from wire if you pulled the two bottom legs apart a bit, or a kind of shepherd's crook.
