Which of these is a mythical creature?

I'm expecting my garden gnome to shapeshift, so far, he's done nothing.

HighHawk, and then I have my daughter, cooking garlic chicken on a wood stove!

HighHawk, and the great Terry Pratchett invented the Pict sies!

HighHawk, laugh. Mixing up brownies, the household denizens, Not pixies

So easy no one should have gotten that wrong

HighHawk, I love how the garden gnome in Simon's Cat fishes in the pond. The cat is always interacting with it to get a reaction. But nothing ever happens.

HighHawk, Funny. 😂
