Why is it so ugly? Sproink is 10/10 but Grumpig has no coherent theme and loses the colors of its preevo entirely. It's like they said "Let's make Pig Miltank" and then completely fucked it up.
Nobody likes Grumpig and statwise the highest it's ever been is UU, and that's in the generation it debuted in. It ruined Sproink and without an evo (which is never going to happen because lol Kanto) it's just another forgotten shitmon.
