Mobility and environment may have something to do with it too. I'd imagine most aquatic Digimon would be found in more aquatic environments, which this place- [He chuckled a bit.] -really isn't. It's possible this just isn't the right habitat to see many, Chosen partners or otherwise.

Seadramon, huh? That sounds pretty cool. I wasn't even aware there were eel-like Digimon, though I'm happy there are.

[You aren't aware of most types of Digimon Chris, hence this post.]
