Swimming (泳ぎ) is a technique that was originally planned to appear in Super Smash Flash 2. It was initially revealed alongside Planet Namek in the fifth Smash Flash DOJO!!! prior to its sixth renovation, but its current fate is a mystery. It would have allowed characters to float in certain bodies of water on stages such as Planet Namek upon falling into it. It would also be possible to jump out of the water, and it was implied that remaining in the water for too long would cause the character to sink into it.
