>>47760972The water strider.
Gen 3 comes a long and gives us our first Bug/Water type with Surskit, based upon the water strider insect, only to have it lose its secondary Water typing for whatever reason upon evolution, becoming one of the ever over-done Bug/Flying types.
As if that wasn't insulting enough, its evolved form is no longer even a water strider is instead some sort of bizarre made up bug that flies with its legs after they become flat and paddle-shaped upon evolution and gets a huge head with enormous antennae that resemble angry eyes.
We wouldn't get another shot at Bug/Water type for another 4 generations, and while Araquanid and Golisopod are both cool, neither of them are water striders.
