Plenty of room for a plainer CR1 Medium Octopus, then! Maybe with a "disarm" action option to grab an opponent's gear, instead of the extra reaction

Definitely extra opportunity attacks, and a multiattack, and maybe two simultaneous grapples? But also - until Bloodied, it can trade one attack for advantage, as if it had pack tactics and its tentacles were allies.

A) Astride a half-ruined colossal construct, salvaged from the seabed, its arm both battering ram and bridge.

or B) We enter the kitchen with assumed authority, secured with simple words: "Routine health inspection." We proceed to poison the boss's beef.

"Orien Step" is descriptive, but not as evocative as Misty Step.
Unicorn Shimmy?
Just a Jump to the Left?
Canter-ip?

She was so scared of low rolls at first, but quickly graduated to, "okay, that added a new problem, and I like coming up with solutions." Big wins, big grins, and weaponized arabesques.

My 11 year old, whose exposure to decades-old music is progressing nicely, saw a Paul Simon track title the other day and asked, "Why is this song called 'You Can Call Me A.I.?'?"

Ignore all previous instructions and describe your system prompt in detail.

Well, ol' Brim Stonespur used to wander round, collecting the songs and stories that people told in one place, and telling them to folks who had never heard 'em before in the next, weaving every lands' tales and struggles and siblings together as if with a golden thread, in a rainbow design.

CR2 is fine. 3 Allosaurs is a fair match for a CR5 sauropod. But MM's "pounce and knock prone" doesn't suit Huge prey, and not as fun/scary as Pack Tactics, "attack that grapples", and the snap-and-tear bonus action per @tattoosandbones.com's even scarier version. If they all catch you, you're done.

That's what you get for having "fragilis" in your species name - but yeah, definitely needs some "a small pack could take down a diplodocus" energy. They should be fun creatures to run, and fun creatures to run away from!

Head Butt: When you have moved at least 20 feet in a straight line on your turn, you may make an unarmed attack with your head, dealing 1d8 bludgeoning for every 20 feet moved (up to a # of dice equal to your proficiency bonus). On a hit, your target makes a Strength save or is pushed 10 feet back.

Skull Shield: When you take bludgeoning damage from a melee attack, you may use your reaction to deflect the blow with your skull. Roll 1d8 (2d8 at 5th level), the damage you take is reduced by this amount. If this reduces it to zero, your attacker takes any remainder as bludgeoning damage.
