Rolling all over each other, pouncing as kittens or puppies would do. There appears to be gentle biting around the neck. The otters emit the chirp sound which I heard in November. The otters fall into the water. Not separately, but in a big bundle of fur.
Play continues in the water.
Tails are flying and I can't see one otter from the other. I am unable to describe their antics further. Darkness arrived and things became quiet. I have no idea where they went. I had a full 30 minutes with them.
