I know I've said before that MIKE, LU & OG feels more like an abandoned Nicktoon that Cartoon Network adopted, between the Klasky-Csupo-esque character designs, Nika Futterman and Nancy Cartwright voicing two of the lead characters, and the cast of characters consisting of precocious kids and quirky/eccentric adults, but watching a couple of old episodes the other night, I came to notice that the overall look of the show seems very ARTHUR-esque as well: the animation has those disjointed outlines that ARTHUR uses in imitating Marc Brown's illustration style, and the backgrounds and layout have that same kind of watercolor illustration look ARTHUR is known for as well.
