Why can't we all just accept that Mr. Bubbles is a Leviathan? The anatomical similarities are obvious, and anyway, it's not as if a Leviathan HAS to be able to swim. Remember Purple Ludroth and Kuarusepusu?

(Admittedly, Kuaru is supposed to begin its life cycle in the water before migrating onto land, but still. The adults don't swim. Yet it's a Leviathan.)

If you ask me, this ongoing argument is extremely stupid. Mr. Bubbles is a Leviathan. Capcom says so. End of story.
