Creatures with Illusion magic at will?

[Bookwyrmm]

Anyone have any ideas on low CR critters that can cast at least Minor Image at will? I know I can make a level one wizard that can do it, but hoping for a non-class based solution. I had a vague memory that one of the wee dragons could, but turns out that is not the case at all.

[HappyDaze]

Forest Gnomes can do it.

Use pixies but replace druidcraft with minor illusion?

Illusion-casting rats always get the cheese, because they distract the cat.

...I may give cranium rats minor illusion now in my games. ...assuming they ever come up.

Apropos of nothing:

any NPC warlock of at least level 2. Then they can have the Misty Visions invocation for at will Silent Image

I don't know if they've been ported to 5th edition, but earlier editions had an aquatic beholderkin creature that could use low-level illusions at will.

High elves get a cantrip. Nothing stopping you from picking that one.
