The June 13 DB is like the old Sunday comics, needs coloring.
A Solution: Coloring eliminates the 3 in R3C7, solving the puzzle.

I found what I think could be termed a "Kraken Sashimi x-wing 3" or a "Kraken skyscraper 3". The four pattern cells involved are in r3c27 and the fin is in r5c2.
Viewed as a Sashimi x=wing, the candidate deletion is r9c1.
Viewed as a skyscraper, the candidate deletions are r9c1 & r7c8.
In both cases, if the fin is true then all candidate deletions are also deleted to solve the puzzle.
(3)r5c2 - (3)r3c2 = (3)r2c1 - (3)r9c1 = (3)r9c7 - (3)r7c8.
