I'm accustomed to finding UR Type 1 and BUG+1 patterns along with fish and a few other techniques in your puzzles. However, the UR Type 2 was a complete surprise in this puzzle. Of course, the reason it was a surprise is because I just added that technique to my solver. Nice timing on this puzzle!

Good timing indeed. I am aware of UR up to 4, Bug up to 3. I don't always see them. <LOL> I miss easier stuff too.

I like it because I found a "squirmbag" (5X5 pattern) and used it to solve. I think that means I missed a Jelly but I like those also.
