Is Corpse Flower the only non-undead that can make an undead creature (excluding spells)?

Is the Corpse Flower the only creature that isn’t the undead-type to be able to make any sort of undead creature?

I mean by means other than the ability to cast spells and one of those spells might be a spell like Animate Dead.

I’m looking for other creature’s abilities, lair actions or diseases or magic items that aren’t simply vectors for spells like a Spell Scroll of Animate Dead.
