"Seel hunts for prey in the frigid sea underneath sheets of ice. When it needs to breathe, it punches a hole through the ice with the sharply protruding section of its head."
Seel is...well...a seal. Like, seriously, that's what it is. It's hands down one of the most faithful representations of a creature from our Earth in the world of Pokemon. In fact, aside from face and size, it could easily be put in our world and no one would blink an eye. In fact, I bet some people would want a Seel or a seal. Just saying.
In Pokemon GO, Seel's Basic Attacks are Ice Shard and Frost Breath, while its Special Attacks are Aqua Jet, Icy Wind and Aqua Tail.
