In “Madness” replace “which is an action where that Fishing Contestant may spend any positive amount of their Energy to subtract an equal amount of their Madness, to a minimum of 0 Madness” with

which is an atomic action where that Fishing Contestant may spend any positive amount of their Energy to reduce their Madness by the amount of Energy just spent and additionally spend any positive even amount of Doubloons to reduce their Madness by half the amount of Doubloons just spent, all to a minimum of 0 Madness

in the same rule replace “except that the amount of Madness subtracted is only half of the Energy spent (rounded down)” with “except that Doubloons may not be spent”
