Not much is needed to @releasethekraken but reeling them in is another matter. Then again, I haven't seen them around lately, so perhaps they have indeed returned to lurking in the depths. Even so, I felt a tribute was due.
In this case, the octo being released is Fiend Kraken — https://yugipedia.com/wiki/Fiend_Kraken — (hide your Sparrows). It's a pretty weak card, but it does have the distinction of appearing in the anime as one of Mako Tsunami's key cards which he used in his duel against Yami Yugi.
