	A configuration with 2 boxes sharing the same 2 columns (swap boxes 4 and 5 in the diagram above) would not work ~~either~~, because ~~a hidden single is detected~~ in the ~~remaining~~ column ~~intersecting those boxes. This isolates the 2 boxes from~~ the ~~2 rows~~.		A configuration with 2 boxes sharing the same 2 columns (swap boxes 4 and 5 in the diagram above) would not work, because locked candidates in box 3 + row 3 would eliminate the last candidate from column 3, leaving the puzzle unsolvable.

The '''Franken Jellyfish''' is a [[fish]] pattern of the [[Franken Fish]] type. This type allows either the [[defining set]] or the [[secondary set]] to contain [[box]]es, as well as [[line]]s.

This is a [[project:fish diagram|fish diagram]] of a Franken Jellyfish:

[[image:franken jellyfish.png]]

In this example, the defining set contains [[row]]s 2 & 8 and boxes 4 & 6. The secondary set contains [[column]]s 2, 3, 7 & 8. All the [[candidate]]s in the defining set (marked with '''X''') are located inside the secondary set. The remaining candidates from these 4 columns can be eliminated.
