philippe eko eel didn't actually go to another dimension he just returned to a more naturalistic environment for his species (eel) and went back underwater. there are a bunch of physical constraints that make hockey relatively difficult underwater but philippe eko eel, fresh off his newfound fame and acclaim in the human world playing the sport, made it his mission to bring hockey to the rest of the eels underwater. this does actually beg the question of how philippe eko eel learned about hockey in the first place if its completely unknown to eels but we'll save that story for another PT. anyway philippe eko eel realized that most of the equipment and gear would be pretty easy since there's so many different kinds of coral and assorted vegetation it's easy to replicate pucks and sticks and even sweaters and helmets. the most difficult part was the ice, of course. he and his eel friends smoothed out a big section of ocean floor to make it smooth and rink like and then they recruited an oceanic bottom-dweller called the Frosty Fish to blow on the section continuously to make it icy enough to skate. there were other issues like the rest of the arena also being water. hmmmm. work in progress i guess. but water hockey went quite well!
