I might be pooched on this one. It's "GARPS", actually.
I'm trying to save "RAILCAR" and "SPACEAGE" on the crosses, and the plural comes from ALLOWS, so that can't be tweaked either.
If I change SPACEAGE to SURCEASE, GARPS morphs into LORUS (largest species of sea gulls), so that's only marginally better imo, plus I've now got the ugliness of SURCEASE to deal with.
The rest of the puz is rock solid (or as near as my ability can get to that state).
Yah I know, I'm pooched ...
