Yes its an amphibian. Quagsire is an amazing. Blanket check to many common offense threats in Tyrantrum, Salazzle, Blastoise, and Doublade, thanks to its amazing typing and ability. Unaware means teams who rely on set-up to make progress are completely unable to break past Quagsire cores. Quagsire's movepool only further allows it to be an annoying wall, most commonly using a great STAB EQ and obviously Recover, Quagsire can be seen using Toxic in combination with Protect, although Encore, Haze, Scald, Curse, and Infestation are all amazing options. Encore is my favorite move on Quagsire to punish those trying to abuse Quagsire's passivity. In this
replay we can see that both Quagsire AND Salazzle put in an incredible amount of work together to shut down opposing offense and overwhelm opposing defense.
