SharkScript

SharkScript is an esolang by User:Esolangist.

Memory

The memory is a 2D "sea" (many tapes, ∞x∞ square) with a "shark" (memory pointer) and "fishes" (values)

Fishes

Trout - 0

Cod - 1

Salmon - 2

Tuna - 3

Halibut - 4

Seahorse - 5

Carp - 6

Parrotfish - 7

Lanternfish - 8

Anglerfish - 9

Bass - Decimal point

You concatenate them, so 255 would be "a Salmon and a Seahorse and another Seahorse" and 123.45 would be "a Cod and a Salmon and a Tuna and a Bass and a Halibut and a Seahorse".

! - eat the fishes on the current tile, outputting them as ASCII

? - ask your fellow shark friends for a number, then some fish appear where you are
