D&D 5E (2014) Which common monsters/creature types do you exclude from your campaigns?

[Arilyn]

It’s the only logical name for a bear with an owl head.

I've started to call them bearowls without even realizing I'm doing it!

 

[GuyBoy]

I gave up on swarms too, except I do recall an adventure that had a flesh golem with a hellwasp swarm inside it, which was pretty grisly!
I adore beholders, they are just so D&D.
As are owlbears; I’m running Phandelver for my grandkids and 8 year old Orla was shrieking with excitement when they encountered and slew the owlbear in the ruined castle.
“ We killed an owlbear We killed an owlbear!,” she yelled excitedly. Intrigued about how she clearly knew about owlbears despite never playing before, I asked her about it
“ Oh, everyone at my school knows about owlbears,” she replied.

After learning about feathered dinosaurs and seeing various big clawed hairy depictions, Im convinced that Owlbears are a dinosaur species and IMC I’ve also made them a more primitive, robust ofshoot of Griffons AND Aacorocka.

What are they teaching kids in schools these days?

I find it fascinating that they've entered into mainstream popular consciousness. What next, flumphs showing up in nursery rhymes?

There was an old flumph from Hanover...

When I was still teaching kindergarten about 8 years ago, I went online to look for "K is for...." colouring sheets and found "k is for kobold." D&D kobolds they were too. And it was just a typical education site, not a nerd parent one.

My only really limit to monsters is based on what's missing from my miniature collection.
If I have a mini for it, it'll be found somewhere in the multiverse.

That's why I use abstract tokens.

They're really cool looking tokens!
Using minis for me isn't really an issue, with the amount of random mini sets that have come out since the start of 5E there's very little I don't have available these days.
