I love kappa.
They're cute, but cool.
They're quiet, but strong.
They're sometimes known to emerge from Japanese rivers and drag unsuspecting, at-play children down into their murkiest deep blue depths, and after successfully drowning their helpless victim(s), these child-like creatures commence in a nigh-cannibalistic feeding spree on what is more-often-than-not confused for a weak kappa being furiously consumed by its former school of fellows, at least, as is discerned between plumes of freshly red-wrought river.
That last part is unrelated to why I love kappa.
