As everyone has noticed, Palpitoad has the least screentime and appearances of all of Ash's Unova Pokemon. I am guessing its mainly because its another water pokemon, and with Oshawott being the star, Palpitoad doesn't have much to do.
What I don't understand is why they don't focus on it more. It's facial expressions are very comical, I could have easily seen it being the next Corphish if it were Ash's main water pokemon this gen.
At this point Unova is over, and Palpitoad seems like it's "just there." What do you think?
