Jumps between tree trunks

The demon let out a croaking scream at the impact but only clamped down tighter. So I slammed it against the tree again, dazing it. Then, harnessing energy in my breath once more, I bounded against one tree trunk, then another, then straight up into the air. Sometimes when My Friend and I went camping, I would do that and leap out over the lake, just to see how high I could get. My record was nearly twenty feet.
Of course, I hadn’t been terrified then. This was more like thirty. And I came down on my back.
There was a crunching sound, and suddenly the claws were gone and my back was marinating in ectoplasm.
