I almost feel sorry for the submersible - in the third panel, it looks like it has tears in its eyes as the kraken's tentacles burst out of the ground, as if it knows its doom is nigh, despite its frantic desparate attempts to escape.

On the other hand, the kraken is licking its mechanical beak in preparation for a bountiful feast of metal whale meat. Given it's one of the fun Heterodynes' creations, I wouldn't be surprised if it had an external speaker to allow it go "OMNOMNOM" as it chowed down.
