I made another anniversary-type post back there having to do with Mecha Knights, and that ties in to this just a bit.
Dread Velvet is an evil Red Velvet cupcake about half the size of a regular Knight. It possesses the same attack capability as a Creep Cake, but with the addition of being able to occasionally inflict Curse. Its primary method of attack is possession of other entities to serve as armor. It also has a ton of HP.
Interesting concept, but in order to be actually intimidating as a miniboss, there needs to be a bit...more to it.
