I am reminded of a scene in the 1994 animated series The Tick:

Barry (trying to crush the Tick beneath his vibro-shield): "Give up being the Tick!"

The Tick: "No! IT'S ON ALL MY STATIONERY!" (2nd Millennium joke, from when people used to write/print messages on a non-electronic medium made of pulped, flattened wood and called stationery or paper....)

I remember seeing that twenty years ago and thinking, couldn't they just compromise? I mean, they're different colours; Barry could call himself the Red Tick and the Tick, whenever confusion might otherwise occur, could call himself the Blue Tick!

Similarly, since Raven has every right to call her fluke Calypso, she shouldn't just scrap the fluke as a customer option. She could keep the name and, when clarification is needed, give it a prefix such as Tropical Calypso, Moonlight Calypso, Paradise Calypso, Sands of Time Calypso, or even simply Merbella Calypso​!
