Kraken type 2: Finned Franken Jellyfish: box 7, box 9, row 2, row 4 and col B, col G, col H, col I on 8
The fish value must either be in the Fish or one of the fins, and an XY consequence chain means either case makes the same elimination/s:
E9-6 <- E2+6 <- D2-6 <- D2+8 E9-6 <- E9+1 <- G9-1 <- G9+4 <- H8-4 <- E8+4 <- E8-8 <- E2+8 E9-6 <- F9+6 <- F4-6 <- F4+8 E9-6 <- E9+1 <- E7-1 <- E7+9 <- I7-9 <- I7+8 E9-6 <- E9+1 <- G9-1 <- G9+4 <- H8-4 <- E8+4 <- E8-8 <- I8+8 E9-6 <- B9+6 <- B9-8 <- I9+8
Hence every possible configuration makes the same elimination/s.
Therefore we can eliminate E9-6.
