The Phantom Blot's nephews are identical triplets. These children look like small versions of their uncle The Phantom Blot, also wearing black clothes and never showing their real identities. Their behaviour is similar to that of the Beagle Brats. They seem not to live with the Blot, just showing up from time to time for a visit.

They have an advantage fighting Mickey, because he doesn't dare to hurt them as they are kids, but Mickey's nephews, being the same age as them, can evenly face them.
