(it sucks -_-')
Squirtle has something much better, which is shellshifting. You know, that animation where he goes back in his shell when turning around quickly. Experienced players use this a lot, and it can be used to do better smashes (called Hydroplanning where you go from a shellshift to a Usmash). It is also used for mindgames, to grab and avoid, and also to do something almost like wavedashing, which happens when you go from a shellshift to a backwards crawl.
I probably explained myself poorly, but if you really want to know there's a list of PT advanced techniques on smashboards. Makes you really value squirtle.
