It has a strong tail because of its past as an acrobat, it can use aqua jet to quickly get around and attack, and can even float a bit during sparkling aria (probably thanks to its fairy powers). Bubbles, voice and spirit bombs are all awesome gimmicks. The seal walk wouldn't really be used much for battles desu
