For me, Breathed was doing his best work on the Outland strips, around 1992-1996 or so, that only appeared on Sundays, and were in full color. Ih have collected books of those, as well as several hardcovers (but not all) of the first 10 years or so of Bloon County strips.
Parts of the Outland strips were reminiscent of George Herriman's "Krazy Kat" comic strip pages. I think deliberately, in tribute.
