Jet [>>] (move) The giant squid moves up to 200 feet in a straight line through the water without triggering any reactions.

Ravenous Embrace [>>] The giant squid makes up to four arm Strikes, each with a different arm and against a different target. The giant squid then makes a beak Strike against one creature that it grabbed during Ravenous Embrace. Each arm Strike counts separately for the squid's multiple attack penalty, but the penalty doesn't increase until the squid has made all of its arm Strikes; the beak Strike uses the multiple attack penalty as normal.
