Cargo Ship: CANON with Mr. Towes and his plant, Vanessa. He was singing a romantic song to it, and began to slow dance before Liam walked into the room. Suffice to say, it's the "fandom"'s One True Pairing.
Cliché Storm: Practically every single anime "quirk" known to man is crammed in as far is it will go.
Hell, try and think of any "slice of life" cartoon cliches, you'll find them here.
Ensemble Darkhorse: Even ignoring that he probably is the only character that doesn't have some sort of hatedom,Mr. Towes has become one of epic proportions. He's pretty much universally loved by both the genuine fans AND the series' mass hatedom and there is a mass demand among them that he be given his own show.
Even the creator loves him! (And this is the same person who uses Birch as a sort of Author Avatar}
Fan Nickname: Mr. Towes is affectionately referred to by some trolls as "Sensei Soulpatch."
Fridge Brilliance: This ran for 52 episodes, the same number of episodes of lot of anime series have.
Well 52 Two Shorts episodes, still 26 is still a common number for anime series.
It would also probably help if anyone on the staff had actual knowledge of anime beyond Google/Deviantart.
True Art Is Incomprehensible: In-universe, the reason that Birch lost an art competition to Raffi was that rather than turning up something along the lines of this trope, she simply drew a picture of Raffi (evidently, she wasn't listening to Mr. Towes' directions) while Raffi simply painted a canvas orange.
Uncanny Valley: Good god! They look like marionettes made out of human corpses!
Which is sad, because the character designer has done some decent work in the past.
