Eustace allowed Dojima to use whatever part of him he needed. Normally he would mind so much physical contact, but this was a dire situation and a necessity. That said, it was a bit difficult trying to keep afloat, especially since "treading water" as a half-fish was quite different than with legs. But he managed.

Not that he...really wanted to sing at all. On occasion he might hum to himself or repeat verses of an old song, but never in public let alone another person.
