Pi-like octomino + Block + Beehive = Another funky 22-cell still life.

Derived from this soup:

EDIT: From a reaction, a 10-glider synthesis of a 16-cell still life. Can be reduced to 9 with a way to put the domino spark there. I don't know such a way, though.

`x = 40, y = 36, rule = B3/S23`

EDIT 2: Long shillelagh on dock, apparently doable in 9 gliders by someone who knows their sparks. Cleanup glider shown.

EDIT 4: Reasonably simple blocker, but not an improvement on any existing syntheses. Maybe we'll have more luck if a caterer shows up?
