D&D 5E St. Patrick's Day Adventure Monster Suggestions

[Eltab]

St. Patrick is supposed to have met Nessie. He must have been impressive as all get-out, since she has been hiding from the rest of us humans for generations now.

Start with Plesiosaur stats and give her a Swallow Whole ability. Your pirates might enter the realm of myth and legend.

And if Nessie swims by wriggling instead of using fins, she is the world's biggest sea snake !

Is he? That's a new one!

Anyway, here's Nessie's stats:

Epic Monsters: Loch Ness Monster (5E)

Another modern tale from the British Isles is today’s entry in Epic Monsters as we head to Scotland for one of the only myths that gives it all away with the creature’s name: Nessie the Loch Ness Monster! First reported (along with who knows how many other fictitious aquatic beasts) at the...

I figure beating one hydra is like beating 9 snakes...

Also, don't forget to provide a magguffin that allows clerics and paladins to count snakes as undead for their turn abilities.

Are they detailed in Pathfinder or 13th Age, I know Ive seen them somewhere just cant remember where? Or are you referring to the Reddcape from the linked article?

They are in Volo's Guide to Monsters, pg 188
There is additional information for what happens when they bathe in demon ichor instead of blood, in Descent Into Avernus pg 240

They also carry a new simple melee weapon called a Wicked Sickle: 2d4 slashing, heavy, two-handed

Loch Ness is in Scotland and that was St Columba not St Patrick (although Columba was Irish born)

Anyway the story is that while Columba was travelling through the lands of the Picts he came across a group of people burying a man by the River Ness who had been attacked by a “water beast” which had dragged him under the water. Columba sent his follower to swim across the river and when the beast came after him, Columba made the sign of the cross and ordered the beast to leave and the monster fled - which is why people dont see Nessie now

Yuan-ti. The scenario could involve ridding an island of the yuan-ti pirates known as the Sea Serpents.

Yep. Or just run Against the Cult of the Reptile god.

Thanks everyone for the suggestions. Prepping now for the game tonight. As they party is low level I'm going with a ton of snakes from the appendix in the Monster Manual and a Yuan-Ti Mind Whisperer from VGtM as a base premise for now. The players are going to be on a boat going from one port to another and as I'm not looking for anything too serious I'm totally ripping off 'Snakes on a Plane".
