I've sort of half got this one but not sure of the rest. 31ac Singular crustacean starts off by lifting every claw (8) _C_A_B_E . I think it must be SC_A_BLE because of the first letters of singular, crustacean, by, lifting, every. The problem is I can't work out the middle bit - scramble? scrabble? It must mean claw, I imagine. Thanks in advance for any help.
